Amazon Organization Is Involved in Online Retail Trade Research Paper

Amazon Organization Is Involved in Online Retail Trade - Research Paper Example Amazon manufactures electronics, such as the Amazon Kindle, for clients and provides cloud-computing services. Additional revenue for the company is from marketing services. This is mainly by online advertisement and co-branding of credit cards (Schneider, 46). The company operates in the United States and in other countries such as France, Germany and China. Strategy Amazon usually delivers products to the customers after transactions are complete. This usually takes a couple of days depending on diverse logistical factors that include distance and address. However, the company has introduced a new system, popularly called same day shipping. This enables clients to buy products online and then the products are delivered to them the same day. This remains its clear-cut strategy to ensure the achievement of competitive advantage. Indeed, the large range of products that it sells is one of the noble strategies that the company is integrating. Buyers can find a variety of products such as toys, electronics, and books that are in excellent form. It customizes the experience of the buyers and gives recommendations for advancement in service delivery that contributes to customer retention. Additionally, it does customer tracking to enable it to gain more customers and retain them. It also gives individuals the opportunity to sell various commodities via its platform (Rosenbloom, 174). These can be either new goods or those that have been used. The advantage that Amazon has had over its competitors is that it does not charge sales taxes. This is mainly because its clients perform online purchasing that ensures effective ordering and delivery of the items with immense convenience. The company’s prior operating strategy was to avoid establishing networks in the nations that have adopted unfriendly tax policies, and thus such states do not have Amazon distribution warehouses. However, the new strategy that it is adopting requires that it sets warehouses across the United States including those tax unfriendly states. This means that the company will give up the lead it has over competitors. However, more warehouses in many states in the US will mean that products are closer to clients thus can be delivered the same day that purchase takes place. This can benefit individuals who are last minute gift shoppers. Local commercial institutions usually push these states to collect sales tax from Amazon because lack of such revenue gives the company a price advantage over them. However, online retailers such as Amazon are exempted from paying sales tax in states in which they do not have physical existence. Currently, Amazon has warehouses in six states and thus contributes sales tax in six states. These are Washington, Kentucky, New York, Texas, Kansas and North Dakota (Rosenbloom, 174). With the new strategy, it will have to collect sales levies in more states. Presently, it is unclear how the strategy will affect the revenues. Effects on competito rs, consumers and Revenues Amazon has eluded charging sales tax from its clients.

Website Migration Project - Term Paper Example It entails the technical, functional and aesthetic factors that relate to a website. The focus of web architecture is on the user and particularly on their requirements. Web architecture addresses this by focusing on the web content, usability, business plan, interaction design, web design and information architecture. Web architecture is also a fundamental concept that includes web site map and website navigation (Linux Home Networking, 2011). In the Tony’s Chips context, the website will be a two-tiered web architecture that entails the web browser that will be used to display the information and content to the different users and a web server that is used to transfer the requested information to the clients/users. Essentially, web pages will be designed using the conventional HTML language, the site will also maintain the initial URL (universal Resource Locator) this will allow it to be accessed and used by users globally. Websites are either internally (self hosting) or externally hosted. Each of these options has different advantages and disadvantages depending on the business needs and requirements. The decision as to whether to self host or externally host a website is dependent on many factors including cost, reliability, convenience, privacy and other ethical concerns. Tonys’ Chips wishes to transfer their website from external hosting to internal (self) hosting. In order to achieve this objective, there are several steps and procedures that must be followed for effectiveness and reliability. The aim is to move the website from an external host to an internal host with minimum or limited down time and disruptions to the normal business operations. Many technologies have been invented that has ultimately made the transfer of web sites from one host to another easier. Despite the leap in technology advancement, there are minimal downtimes and delays expected in the transfer. Such transfers

Research Paper Example Among the main concerns that are raised concerning the move are: what is the main motive of India launching mars orbiter especially with increased space exploration across the globe, and, is there a rivalry in competition between China and India concerning space exploration? Therefore, this discussion aims at establishing reasons why India’s space exploration is such an esteemed undertaking amidst complains on increased poverty levels and substantiate on claims that India invests in space exploration to counter China’s supremacy in space exploration within the Asian region. Discussion In a recent article by MacAskill and Nagarajan (2013), India, have plans underway to launch a space ship ‘Mars Orbiter’ towards Mars as race for space power intensifies between the country and China. The two countries are the recent entrants into the race with US, Russia as well as Europe having already launched space explorers into the mars orbit in the past. It is however wo rth noting that in spite of the open contest between India and China in space supremacy, few or none of the officials in India would not admit this. â€Å"India is clearly concerned about China’s recent rise in space prestige and wants to minimize that damage† (MacAskill and Nagarajan, 2013) as is reported by the report and this illustrates the tag existing between the Asian countries. There have been ongoing debates and research studies aimed at establishing the truth in the postulation that India’s increased zeal to launch the mars orbiter is for competition with China as a rival in Asia as against being propelled by reason of gathering scientific knowledge on existence of life on Mars or even to showcase technology advancement of the country. This study therefore identifies the problem in justifying the motives of space exploration by India and sets forth to substantiate the claim. This therefore makes the question of ‘what exactly is the aim to the gre at exploration investments?’ paramount to the discussion. Besides the main goal of this essay as being to investigate the above posed question, this study envisions to contribute towards bridging the previously identified gap in literature concerning the motives of India launch of the mars orbiter. This study will also guide in future studies in the same theme where the findings will be instrumental in revealing the direction to be taken by future researchers of Asian space exploration in the 21st century. Indian government and the space exploration mission is not based on race towards space exploration supremacy as argued by many. On the contrary, Indian mars exploration is meant to gather scientific information and displaying Indian technology in space exploration. Depending on various literatures available on the topic, there is justifiable evidence to support the postulation above. Technological development as well as social development is necessities for economic growth and development within any nation. India is seen to have increasingly invested in space exploration in the recent past, a phenomenon that sparks heated debates on the intentions while majority of the population in the country still live in absolute poverty. Among many other missions, that India continues to undertake in space exploration in the launch of mars orbiter is a major one. However, with claims circulating that India is determined

Socrates and Plato's Apology Essay Example | Topics and Well Written Essays - 1000 words

Socrates and Plato's Apology - Essay Example Much of this trial is known through Plato’s Apology (Plato, 2009). Socrates is however, innocent of the charges that are levied against him since his beliefs are a practice of his own philosophy, something that was permitted in ancient Greece, and they accept and celebrate the existence of god and the choice of people to follow him or not. His actions, thus, in no way do any harm to the religious structures of Greece. The right to dissent within certain structures was allowed and it is only this right that Socrates exercises in his life and he upholds this right throughout the trial. According to Plato’s Apology, the reason that Socrates cites for his actions is the declaration of the Oracle at Delphi of his superior wisdom over other people. By making this clear, Socrates makes clear his belief in god. The god who is associated with the Oracle of Delphi, moreover is one that is a part of the Greek pantheon of gods. The Oracle of Delphi was associated with Apollo, the s un-god of the Greek pantheon and a very important figure in the mythology of the Greeks. This would make the charges of Socrates’ atheism baseless. By asserting the wisdom of god and his lack of the same, Socrates is able to prove his innocence when faced with the charges of atheism. Socrates points out to the jury that his quest for knowledge and wisdom was essentially based on his belief in his ignorance. This ignorance presented him with a paradox when viewed in the light of the predictions of the Oracle at Delphi (Plato, 2009). An attempt to solve this paradox does not necessarily constitute an offence against god or the laws of ancient Greece. The ideas that Plato and Socrates held regarding ideas and forms entailed the superiority of what lay in heaven rather than what was present on earth (Plato, 2004). This meant that they did not malign god or question the existence of god. What they did during their lives was to affirm the presence of god in a way that was in a lot of ways, scarcely different from existing perceptions. The charges of atheism that were leveled against them were thus, not true and were based on an incorrect or incomplete understanding of their philosophies and theories. Another aspect of the case against Socrates was the allegation that he corrupted the youth with the power of his ‘sophistry’, which in those days meant a glib manner of talking that was designed to persuade a person to perform certain actions. It also had negative connotations in those times. Sophistry was considered to be the practice of the orators of those times who sought to sway the masses and the jury for their own purposes. Socrates distances himself from such accusations right at the beginning by appealing to the jury to look at not his eloquence but at the truth of his statements. Socrates counters this claim successfully by appealing to the jury to look only at the truth of his statements and not at the manner in which it was communicated. He also points out that the perception of his sophistry was built up as a result of the works of people like Aristophanes who sought to mock him with what he perceived to be cheap attempts at comedy. A brief look at the works of Aristophanes would make it clear that the claims made by Socrates in the trial regarding the attempts of people to paint him and his followers in a negative light are true. The novelty of the ideas that Socrates thought of

Internet Gaming Addiction Essay Example for Free

Internet Gaming Addiction Essay Computer games are software which developed with an interesting plot, amazing graphics and unreal concepts which you may only see in those games, fantasy movies or animated movies. There are many types of computer games. There are some games that are really addictive making players unhappy if they were offered just a nick of time for playing. Some computer games drive and put the player at the highest level of eagerness to finish the game and wait for the next version. These games are addicting for only a short period of time, and stops after finishing it. The bad thing here is when the player starts to look for another game similar to his previous game. This surely is a sign of addiction. These computer games have characteristics that may or may not be experienced in real life. The difference of these games from the real world is that it makes the user do virtual things that people don’t do in real life. These games are designed to entertain people and one of its objectives is to make people hooked to it. If there are more people hooked, then the producers of the games get more profit. How did these games appeal to the people? Some games may not have done its objective but there are some that greatly caught the attention and time of the people who played it. Another thing is that these games offer competition. It is the same competition that we experience in real life. If the player performs well over the other players in the game, he feels satisfaction. In order to stand among the rest, a player needs to play hard or devote more time. It is just like when we want to standout in class, we have to study harder or when we like to be the most outstanding player in our favorite sports, we have to practice more. A person gets satisfaction after achieving something that he or she wants. This achievement is easy to acquire in computer games as compared to real life. You just sit down, run the game, and enjoy yourself while achieving your goals. However, computer games are far from our real world. You may relate to them, but the real thing is really different. Sometimes, the things that happen to your character in a role playing game may resemble the exact opposite of what is happening to yourself. When your character in the game gets richer, it does not follow that it could happen to the real you. Actually, it does the other thing – you become poorer. Getting addicted to these computer games may be enjoyable but there are serious consequences. Addiction always leads to negative effects. It renders a person irresponsible and makes him forget more important things he should do, and worse, people who are close to him. Sometimes life itself could be just thrown away like a disposable item. A South Korean man was reported dead after playing online game continuously. The death was caused by heart failure due to exhaustion, lack of sleep, and not eating enough (BBC News, 2005). Not sleeping or lack of sleep leads to failure or weakens the capability of our body to resist sickness. And gamers always force themselves to play up to the point that they even lose the time for sleeping. If normal people who lack sleep do not feel good sometimes, then this fact also applies to the gamers. Playing computer games is not for free. It uses electricity, some needs Internet connection, and sometimes you have to pay the game servers to play their online game. Living our daily lives is not for free either. We need resources to support our needs. We need to work to earn resources. Lucky are those teenagers supported by their parents. And obviously those parents will not support for addiction to computer games. It is also a reality that we may earn money from playing games because there are things in a computer game especially in online games that can be traded off with real money. But this money is not enough to support our needs. Addiction to computer games, generally, will not do good effects to the people. If you want to play computer games, you can play them. But be sure to remember not to fall on its trap on becoming addict to it. It has never been good to be an addict on computer games or anything. The only problem is, sometimes, you tend to ignore things because it is being blocked by something attractive or enjoyable. Being responsible is the key to avoid addiction. You better think of yourself, your family and your future. Do not let yourself get entangled in the roots of addiction. You should balance all the things that you do. Do not forget to be happy or do necessary things for your own life. You should know and set priorities in life. You should ask yourself what is important. Think critically, responsibly and do not stop with that. Whatever might be the result of that thinking, carry that on. Just plant in your mind that being an addict to whatever is not good.

Does Democracy Ensure Free

Does Democracy Ensure Freedom Essay Does democracy ensure freedom? I believe democracy can ensure freedom, but not always, thus my answer is maybe. For democracy is a form of government that rely on a system of law in which individuals are treated equally while having fair access to the legislative process through electing official who will act in their constituent’s interest and voice their concern. Through proper protection with legislation, individuals freedom can be ensured. Yet the nature of democracy favour majority thus it is possible for politician to cater to the mass to secure vote and have access to the seats of power. Democracy is unable to act if the votes are tied, such flaw can leads to politician abuse their power tilting the result either way to further his own goal. If elected official no longer voice the population yet game the system by continue to appease the majority, minority right and freedom can not be ensured. Government ultimately objective is to govern the people for the betterment of people, thus democracy reflects the need for it is form of government allowing peoples voice being heard through the elected officials. Each voters vote count and the majority trumps. Elected official then go on legislate laws that regulation that resolves the populations concern. Such fair access to the legislative process and equality before law ensure the population to be protected, the law are made by them and for them, protecting their freedom and rights. But democracy also follow majorities rule. It is possible for 49% of population to lose out simply because of the 2% difference. Yet if rights are cemented fully protected via charters, even minorities can escape such tyranny. Unfortunately, elected officials can not always complete reflect the desire of the entire population. They are at best incomplete projection if not catering to special interest or simply the mass for the system favours the majorities, and once tied vote occurs. The decision will lie solely on those in power. For few individuals to be able make decision that influence a nation, such power can be attractive if not lucrative, for there is motive and it is not hard to imagine such corruption taking place. Once a politician is no longer serveing the voter but himself, without proper check and balance for the government to self correct such mistake. It is to picture minorities right and freedom being sacrificed for the corrupted official to stay in power. The key all hinges on the soundness of said countrys legal system, if a government official have the power to alter laws, taking away rights and freedom as he pleases. The freedom can not be ensured. Yet, with a proper procedural fair legislative system, the inbuilt checks and balance will stop said corrupted official overstepping his position. The electoral system will kick in which official will be replaced if they do not deliver what is expected off them. With a solid charter of rights, even minoritys innate rights and freedom can be protected against majorities for the inalienable rights protect each of us and allow us to maintain the dignity we all possess. Freedom is the concept that verges upon the condition in which individual live their life accord to their free will. For they make their own choices without facing disabling condition nor the pressure of simply fulfilling the basic necessities of life. We choose how we present ourselves to the world and how we communicate our idea and thoughts. We decide on how to live our life, from our goal to our means of achieving said goals. Yet these seemly innate right are in fact fragile and vulnerable. The nature of government impose rules and regulation with our daily life. Our freedom is merely conditional, for we can only exercise our right and freedom to a certain extent. As matter of fact, our right and freedom can be taken away by the same law that protect our rights and freedom. But that is the truth of reality, freedom without bound is impossible. The physicality of reality impose restriction, scarcity of recourse and mortality of men. Civilization dictates rules from punishment of crimes to shame and guilt through morality. Thus government, a form of rule, can not truly ensure freedom for its conditional and with limits. Men has long realize such limitation, yet we still yearns for such notion for we are driven by our free will and we seek create such system for we are protected from not just each others but ourselves own infringement of rights and freedom. Democracy is still our best attempt at this unrealistic dream, the approach is simple, for a system of law made by people for people. We strive to effectively govern ourselves and keep our right and freedom. It is understandable to treat the question â€Å"does democracy ensures freedom ? † in an bifurcate manner. It is easy to state the fact that democracy is simply mob rules thus two wolves can vote having the sheep for dinner against the one lone sheeps objection. Yet it seems silly to categorize a whole countrys population into a predator/prey relationship, not to mention having a sound legal system in which inalienable rights of human beings are guaranteed can indeed prevent the two wolves ganging up on the sheep, minorities can still be sufficiently protected by law if the charter of rights allows. Further more, freedom can only be secure via proper system of law that protect human right and freedom, types of government should not be the deciding matter for ensuring freedom. As the above paragraphs have shown, democracy either ensure nor deny freedom, while there is no true freedom under any form of government for by definition of government, restriction and restraints are naturely imposed upon individuals. I still consider limited conditional freedom preferable to none for my inalienable right are protected even against the tyranny of majorities for this rights are inalienable. While democracy can allow favour toward the majorities and official in position of power, with proper checks and power established within the government, such issue can be self corrected. But without the legal safenet, minorities can easily been swapped up by politicians agenda and sacrificed to the tyranny of majorities. As a partying thought, if no form of government can achieve true freedom, what is the future of democracy with our society?

Separating Mixtures Back Into Their Components | Experiment

Separating Mixtures Back Into Their Components | Experiment Abstract To separate these mixtures it was appropriate to understand the physical and chemical structures of all the substances situated within the mixture. After separating these mixtures based on their physical and chemical properties; it was then appropriate to compare their experimental masses compared to their actual masses. Once separating these mixtures and comparing their masses it was important to record any discrepancies which may have been observed throughout the experiment. Background Information The mixture was composed of the following substances; 5.5g sand 2.4g iron fillings 25ml methylated spirits 13g of NaCl 0.6 g of sodium sulfhate 13ml of hexane The aim of this experiment was to separate a mixture back into its original components based on the mixtures physical and chemical components. A mixture is when two or more substances are combined by forceful means, such as pouring substances into a container. The molecules of the combined substances then mix with the others to create the forms of solutions, suspensions and colloids. These mixtures can be classified as homogenous or heterogeneous solutions. A heterogeneous mixture contains unevenly distributed liquids, gases and particles. The sand, iron, and hexane are all immiscible substances when mixed in the mixture, therefore many unevenly distributed particles and liquids are present in the mixture, thus categorizing the mixture as a heterogeneous. Mixtures usually do not consist of chemical bonding between the substances, thus allowing the mixture to be separated using simple methods of filtration. As the mixture contains sand, iron, hexane and methylated spirits basic filtration can be applied based on each substances chemical and physical properties. However as NaCl and Na2S04 do undergo chemical reactions with the water present in the mixture; this creates a barrier for any type of filtration. It is therefore appropriate to analyze the chemical and physical properties of each NaCl and Na2SO4, and find an appropriate method to extract both miscible substances from the mixture. Therefore it is applicable to note that substances are separated based on their chemical and physical properties. Therefore analyzing the physical and chemical properties of each component situated in the mixture, appropriate separation techniques can be identified. The most obvious separable substance situated in the mixture is Hexane. Hexane is oil, used for many necessities of life, such as cooking. As seen in figure 1, hexane has the chemical formula C6 H14 and it only contains hydrogen and carbon atoms, thus putting the solvent into the category of an alkane (hydrocarbon). Hexanes chemical structure is dependent on its alkane properties; its hydrogens are exclusively linked by single bonds to carbon, this is also known as a covalent molecule. As the electrons are being shared this creates similar charges for the hydrogens and carbon atoms. As both atoms electrons have similar negative charges they repel each-other and create a non-polar substance. As non-polar substances are immiscible in water, hexane will not mix in water as its a non-polar molecule. Instead of mixing in water, hexane with a light density of 0.654g/ml will sit on top of the water as water has a heavier density of approximately .995g/ml. In contrast to hexane, water is a polar molecule. The two oxygens bound to the one hydrogen create a V shape with the hydrogen atoms. As seen in figure 2 it is noticeable that when hydrogen atoms bond with oxygen, the hydrogen releases one of their electrons to form a covalent bond. Due to hydrogens electrons being attracted to the positive electron oxygen, the two hydrogens become slightly positively charged, and the oxygen then becomes negatively charged. (www.ozh2o.com, 2003). The dissociation of the positive and negative charges produces a polar molecule. Due to the above mentioned physical and chemical properties of hexane and water, the most efficient way of separating hexane from the mixture, will be the use of decanting. And also using a separation funnel. Decanting is the process of carefully pouring a lower density liquid off the top of another, such as hexane and water. It is poured into another beaker and then separated again using the separation funnel. A separation funnel is used to slowly and carefully drop by drop separate the heavier in density substance (water). Another substance that is present in the mixture that is also miscible in water is sand. Sand also known as silicon dioxide has a chemical formulae of Si02 and has a tetrahedral chemical structure, as seen in figure 3. Figure 3 clearly shows the four oxygens surrounding the central atom Si which creates a triangular shaped structure; hence the reason silicon dioxide can be classified as a tetrahedral crystal. Out of all the silica crystallines, on average only two out of the four oxygens of the Si04 are shared with others, giving the formula Si02 (book reference). Due to sand sharing pairs of electrons between its atom it consists of having an extensive covalent chemical bond. Its extensive covalent chemical bonding creates a strong bonding with the elements oxygen and Si, thus meaning the chemical formula Si02 is a strong element. As sand has a hard quartz figure it is insoluble with water, therefore separating sand from the mixture filtration can be used as it separates the liquids from the hard solutions. Another solution that has a hard like figure and is insoluble to water that is in the mixture  is iron fillings. Iron fillings are composed of iron or Fe. Iron fillings are a type of ferromagnetic material which can be easily attracted to a magnet. The electrons orbiting the iron atom resemble a current, thus this results in a small magnetism to each individual electron; this can be amplified by the spinning of the electrons. This then means the tiny pieces of iron can transform to a tiny bar magnetic when a magnetic field is in area of them, thus irons opposite ends attract to the opposite ends of a magnet. For example the north end of iron would be attracted to the south end of the magnet. As iron is also a substance that is insoluble in water the method filtration will be most effective to separate the iron from the mixture. As iron is already classified as a ferromagnetic metal, this means its domain already consist of a high degree of magnetization. However as seen in figure 4, when coming into contact with a magnetic field, the domain become randomly orientated. Also when iron comes into contact with a more modest magnetic field the domain can become aligned in the direction of the force. As both sand and iron fillings are insoluble in water, they will sink to the bottom of the mixture not having a chemical reaction with any other substances. This sediment at the bottom of the mixture can be separated first using filtration as the sand and iron will be trapped in the funnel paper. However to separate the sand from the iron, using a magnet will be appropriate as irons domain will be attracted to the opposite end of the magnet, as seen earlier in figure 4. As seen in figure 5 filtration is the use of a funnel, funnel paper and a beaker. The beaker is used to catch the mixtures liquids and the funnel paper used to stop and absorb any fine sediment, in the case of the experiment iron and sand. Once the mixture is poured  through the funnel paper the sand and iron will be left on the funnel paper and the mixture will be separated from the iron and sand in the beaker. It will then be appropriate to use a magnet to separate the iron from the sand. However as the sand iron will be wet, leaving the mixed solution of sand and iron to dry will be appropriate. Magnetic separation consists of using a magnetic to attract the ferromagnetic metal iron. As seen in figure 6, once attracting the iron from the sand, the iron will be on the magnet and very hard to separate from the magnet. Thus using glad wrap over the magnet the glad-wrap will be easily removed from the magnet as it is nonmagnetic and the iron fillings would be easily poured onto a watch glass. Once extrapolating the obvious and simple substances from the mixture, it is then appropriate to separate the methylated spirits. Methylated spirits also known as ethanol is a alcohol which consists of a certain percent of methanol added to it to create a poisons drinking substance. Methylated spirits is a polar molecule, its hydrogens, carbons and oxygens all distribute positively and negatively charges, thus creating a polar molecule. As Methylated spirits is polar it is miscible in water. Therefore as it is miscible in water the group will find filtering and decanting not an option to separate the methylated spirits from the water. Thus the group will use fractional distillation. However it is appropriate to explain why methylated spirits have a lower boiling point that Figure 7  water and this is all about the chemical structure of methylated spirits and water (H20). Methylated spirits undergo a reaction to form a hydrogen bond. As hydrogen bonds form between Hydrogens and a highly electronegative atom namely, 0, F and N, methylated spirits fall into this category. Methylated spirits contain a hydrogen and a highly electronegative oxygen atom, thus the reaction of hydrogen bonding will occur, this is seen in figure 8. Despite water is polar and also miscible in methylated spirits (metho) it does not have the same chemical structure as does methylated spirits. Water has a smaller structure and can continuously form hydrogen bonds thus enhancing its molecular strength as metho does not continue forming hydrogen bonds. This is shown in figure 9. Both figure 8 and 9 show the difference between the hydrogen bonding of both metho and H20, it is evident that water consists of very strong intermolecular forces as it is continuously forming, however metho has less opportunity for hydrogen bonding, thus its formation in structure is weaker. Therefore it is evident that the metho will need less energy to deconstruct its chemical structure compared to water as it will need more energy to breakdown its strong hydrogen bonding. Therefore based on this information it will be efficient to use fractional distillation as methylated spirits will be evaporated and be collected as the dilute. Fractional distillation is the method of separating mixtures into their original individual components based on boiling the substance that is wanting to be found boiling point. Therefore a thermometer is used to signify the what the temperature of the mixture is boiling at and as soon as it hits the boiling point of the substance wanting to be extrapolated, the gas then rises into a condenser and the condenser then condenses the gas back into a liquid, slowly dripping the liquid back into its original form. As methylated spirits has a lower boiling point (70-80 degrees)than water (100 degrees) it will be appropriate to use the fractional distillation method to find the amount of methylated spirits in the mixture. Two substances that were left in the mixture were both sodium sulfate and sodium chloride. Both these salts are soluble in water due to their chemical structures. Sodium chloride is well known as a halite (rock salt), salt which is situated in the oceans and is more chemically known as an ionic compound. As seen in figure 11, its chemical structure is very strong as it consists of an ionic bonding. The lattice structure of the ionic bonding between the two compounds creates a very strong chemical structure. In return this defines why sodium has such a high boiling point of 1413 degrees as the chemical structure needs stacks of energy to break down the composition. Sodium sulfate with the formula Na2SO, has an extremely similer structure as sodium chloride. At its solid form sodium sulfate forms a white crystal also known as a salt. Its ionic structure very alike to sodium chloride defines the reason why it also has a high boiling point of (..). Both sodium sulfate and sodium chloride are soluble in water. As H20 water is a polar molecule, in other words consists of uneven distribution of charges, the negatively charged oxygen the end of the water is attracted to the positive sodium ion in the salt. As seen in figure 12 the reaction shows the oxygen extracts the lattice structure of in this case sodium chloride, however also sodium sulfate. Therefore putting more water molecules surrounding the salt, enabling it to de-solve. (Wiki answers.com, year unknown). NaCl(s) + H2O > Na+(aq) +Cl-(aq) + H2O Therefore no separation technique can be applied to either sodium sulfhate or sodium chloride as they are both salts and dissolve in water. As they both are miscible in water and impossible to decant, filtrate, evaporate or use fractional distillation. Creating one of the solutions to form a insoluble compound would be highly affected and would then be able to filtrate out. To separate the NaCl Na2SO4 from the mixture, it was evident to use a ionic compound that reacted with an opposite charge, such as +cation attracts -anion. Therefore Barium Chloride chemical formula BaCl has two separate ionic charges Ba2+ and Cl-. These two ions are attracted to their opposite charges when coming into contact with them. This can be seen in the formula below. When adding BaCl to the mixture the following reaction will occur. BaCl2 + Na2SO4 BaSo4 + 2Na+ CL- The formula above represents the reaction of Barium and sulfate creating a solid, whereas the Na and Cl are left by themselves as spectators as they do not undergo a reaction. This then creates a insoluble solution which can be filtrated out using the basic filtration method, as mentioned before regarding sand and iron. Therefore analyzing the chemical and physical components of each substance that is present in the mixture, it was evident to what separation would be applicable to each substance; this can be seen in the flow chart below. It was then hypothesized that based on these physical and chemical properties, each substance would be extrapolated giving a 5% error range for any mistakes made throughout the experiment. Flow chart This flow chart represents what method for each substance was used to separate it from the mixture. Apparatus Evaporating disk Separation funnel Filtration funnel Filter paper Boss clamp and Retort stand Measuring cylinder 5 Beakers 0.6g of Sodium Sulphate (Na2SO4) Atomic weight scales 13ml of Vegetable Oil Spatula Barium Chloride (BaCl2) 1.3g of Sodium Chloride (NaCl) Glad Wrap Electronic heating mantle 5 distillation-tube clips Round bottom flask Condensing tube Thermometer Stand Glass Rod Distillation tube 5.5g of Sand (SiO2) 2.4g of Iron fillings (Fe) Water (H2O) 25ml of Methylated Spirits Magnet Method The mixture was poured into a beaker using a stirring rod for more accuracy, separating the hexane from the mixture. The hexane was then put into a separation funnel with the mixture beaker under the tap, to retrieve any droplets of water that were still in the hexane. Thus the hexane was completely separated from the mixture. Filtration equipment was set up appropriately ready for use. Sand iron was poured through the filter paper (*2) Beaker retrieved all the liquid, thus separating the iron and sand. Sand iron put on watch glass and left over night to dry; enabling separation. Magnet covered in glad-wrap appropriately separated iron from sand. Both Sand iron were put on separate watch glasses. Fractional distillation equipment set up appropriately. Heat box turned on to boil the methylated spirits. Thermometer used to signify the boiling point of methylated spirits. Methylated spirits boiled and evaporated. Methylated spirits went through condenser; gas underwent a physical change back to the liquid (methylated spirit). Methylated spirits separated from mixture and placed in beaker. Using calculations the amount of BaCl that was needed to react with Na2So4 was found Using an electric weighing machine an exact value of Barium was then added to the mixture containing NaCl and Na2S04. BaSo4 became insoluble in the mixture, thus setting up the filtration equipment was needed. Filtration set up for separation BaS04 separated using filtration with two funnel papers and a funnel. BaS04 put on a watch glass for drying. NaCl and water was left in the mixture, thus the use of evaporating was used. Electric heater, a round bottom conical flask, condenser and tubes were set up to evaporate the water from the NaCl. Water was placed into a separate beaker and then placed in the air drying area to evaporate any extra water, leaving an accurate solution of NaCl. Discussion This extended experimental investigation determined whether a substance can be separated effectively based on its chemical and physical components, allowing 5% to pass as an accurate result. Therefore analyzing the results in table into graphs will be most efficient to display the data. Graph 1 compares actual mass to the experimental mass of only gram solutions. It is evident to note that all the mixtures despite the outliers barium sulfate and sodium sulfate are in an error range of 5-10%. The most accurate result was the iron fillings; 99.17% of the iron fillings were extrapolated from the mixture. The 2nd most efficient extrapolated data was the sodium chloride with 96% extrapolated. Sand was also quite efficiently extrapolated however only 89.45% was separated from the mixture. The two drastic outliers did however have a major effect on the hypotheses. As barium sulfate sodium sulfate had only 50% separated from the mixture. Analyzing graph 2 it is appropriate to suggest that the methods that were used to extrapolate methylated spirits and hexane may not have been most appropriate as there was in both hexane and methylated spirits 1 ml missing (4%). However despite this diminutive difference it is acknowledgeable to suggest that the techniques did work as 96% of both hexane and methylated spirits was extrapolated from the mixture. Therefore the hypothesis was proven correct as there was a 4% error. However it is recommended that if the experiment was to be done again different methods of separation may apply to both hexane and methylated spirits. It is therefore appropriate to suggest that the hypothesis was proven wrong as the sand, barium sulfate and sodium sulfate all had more than a 5% error range. Many variable may have caused the inaccurate results of all substances, as it must be notable not one substance was fully extrapolated to 100%. Finding the right amount of each substance was extremely important as it then proved that mixtures can be separated based on their physical and chemical properties. The erroneous results create room for discussion into what may have caused the different result. One major variable may be the use of equipment. Hexane was separated using decanting with a stirring rod and manually pouring the oil into another container, however there was 1ml of hexane missing the reason to why may been defined as not enough care when titrating or maybe the whole techniques was wrong itself.
