Do People Who Are Trafficking Human Organs Help Other People? Essay

Do People Who Are Trafficking Human Organs Help Other People? (Campbell & Davison, 2012), say that the unlawful business in human organs special kidneys has advanced quickly and unexpectedly. The reasons why selling kidneys has advanced quickly is that nowadays many countries have wars so there are many poor people who need money to live a good life. Also, after wars, there are many sick people that felt desperation because they lost their organs in the war and no one donated to them, so they needed to buy organs to stay alive. Other reason is because people have two kidneys so when they sell one kidney for important reasons, they won’t die. Most countries punish those people who sell their organs that are why in those countries there are many illegal trafficking of human organs, but in some countries trafficking human organs is legal like Iran. People who are trafficking human organs help other people to live a good life, also help sick people to feel healthy again and not to die. The desperation of many people needing transplantation s urgery and the poverty of many people with healthy organs often results in the trafficking of human organs. It’s a trade where the two persons win, because trafficking human organs help many poor people who don't have money to buy food or clothes by selling their organs that they can live without for money to the sick people who need this organ to stay alive. Selling organs can help the sick person to stay alive and give the poor person money to help his family from humiliating life.

Hydration Lab Essay

The purpose of this lab is to determine the water of hydration of a compound (CuSO4) by heating it and hence find its chemical formula. It was determined that the compound contained 4 moles of H2O for every 1 mole of CuSO4, hence had the formula CuSO4 à ¯Ã‚ ¿Ã‚ ½ 4H2O and Copper [II] Sulfate Tetrahydrate. However, the literature value was 5 moles of oxygen for every 1 mole of CuSO4 (Copper [II] Sulfate Pentahydrate – CuSO4 à ¯Ã‚ ¿Ã‚ ½ 5H2O). As calculated above in Data Processing, this means that the percentage deviation from the literature value was 20%. This is significantly less than the percentage uncertainty, which was 37%. This should indicate that the random error was higher than systematic error, because while there was a high level of uncertainty, the literature value still falls within that value, meaning that the measurements were close enough. In reality, though, this high level of uncertainty says more about the inaccuracy of the measuring equipment than it does about the amount of systematic error. For example, it is possible that simply not all of the water was removed from the compound. On the contrary, the lab procedure instructed to continue trials of heating the compound and weighing it until the mass values were within 0.05g of each other. Those in this lab were only 0.01g apart – a difference which would not have affected the outcome of the lab. This means it is unlikely that there was a significant amount of water remaining in the compound. Evaluation of Procedure It cannot honestly be said that this lab was executed successfully. This is for two main reasons: 1. the false result 2. the high degree of uncertainty The first of these is surely the most important: this lab did not achieve the desired result. While the compound had a water of hydration of 5, the lab results said that this value should be 4. In some circumstances, such error could be tolerated – indeed, 20% is not terrible. However, the very purpose of the lab was to determine the compound, and this goal was not achieved. The second point is how uncertain the data really was. Based on the percentage of uncertainty, the water of hydration could have been anywhere from 2.5 to 5.5. This does contain the literature value, but has a range of more than half of that value (3/5). If the water of hydration could nearly have been 2 or 6, does this lab truly reveal anything? It gives a vague estimate of how much water there is, but little more. Much of the uncertainty was caused by an imprecise scale used in the initial measurements. Only after the procedure requested precision to two decimal places was a more precise scale used, and the initial measurements were still only accurate to 0.1g. Also, if the mass of compound used had been higher, the percentage error would have been less simply because it would be a smaller portion of the measured value. Improving the Investigation This lab did not meet its goal, hence definitely should be improved. The simplest change that could be made is to use the more precise scale from the beginning of the experiment. This would reduce the percentage error down to 6.7%, a much more reasonable value. This, however, does not solve the problem of the inaccurate value determined, because it is unlikely that this scale would have been any more accurate, despite being more precise. It is hard to pinpoint, therefore, exactly where the experiment went wrong, as it seems that the scales were not at fault but that a sufficient amount of water had been removed. There was certainly some kind of systematic error. One way that this error might be reduced, even without understanding its source, is to increase the amount of substance measured. Because the lab is about obtaining a ratio, this would not affect the result at all except hopefully to decrease the effect of any systematic error. This would, however, have the disadvantage of making the lab take longer, and steps might need to be added to ensure that all of the compound has a chance to dehydrate.
