Conclusion The purpose of this experiment was to discover the chemical properties that copper has when reacting with other chemicals and how it changes physically during these processes. (Department of Chemistry‚ 2013) This was achieved through many types of reactions‚ such as a redox reaction‚ double displacement‚ decomposition reaction and single displacement depending on the chemical properties in relation to copper of the other substances when it was added with copper. Copper was either in an

A novel’s ending plays a very important role on the way it is perceived; for example‚ a novel could have a great plot and character development but having a dissatisfying ending will just make the reader want to toss it directly into the trash can. In his novel 1984‚ George Orwell manages to link the events throughout the novel into the most satisfactory ending I’ve read so far: Winston’s death. When reading the novel for the first time I thought O’Brien actually belonged to the brotherhood and was

In conclusion to the distillation lab‚ I think our data shows that our experiment went well. Our graph resembles the graph in the lab handout (graphs attached to lab notebook sheets). The fractional distillation shows the sharp slope between when the cyclohexane burns off and mostly only toluene remains. The microscale graph seems to be accurate because it shows the large jump where the cyclohexane is burned off. To view the apparatuses used in the experiment look at the attached pictures. To

Conclusion and Evaluation Conclusion In our test we put six different sliced up potatoes chips in solutions. The solution was different concentration of salt and water‚ one was 5% sugar‚ one 10%‚ one 15%‚ one 20% and one 30% salt concentration. We measured the mass of the potatoes chip before and after we put it into the solution. To keep the experiment fair we only changed one variable which was the salt concentration. The results that we got showed the chip went up in mass for 0%

Is Economic Development a Prerequisite of a Functioning Democratic System? In the world of political science‚ it is an inherent feature of the discipline that academics will seek a universally applicable theory to explain phenomena that occur within the political sphere. Seymour Martin Lipset did just that in his article Some Social Requisites of Democracy: Economic Development and Political Legitimacy‚ published in the American Political Science Review in 1959. In this‚ he made the claim that

Africa is the world’s second-biggest and second-most-crowded mainland. At around 30.2 million km2 including adjoining islands‚ it covers six percent of Earth’s aggregate surface zone and 20.4 percent of its aggregate area region. With 1.1 billion individuals starting 2013‚ it represents around 15% of the world’s human populace. Africa’s populace is the most youthful amongst every one of the landmasses; the middle age in 2012 was 19.7‚ when the overall middle age was 30.4. Algeria is Africa’s biggest

Barry Allahyar Dr. Dodd CHEM 2122 2010-09-16 Experiment 19: Fischer Esterification‚ Conclusion The objective in this experiment was to efficiently perform an Fischer esterification of 1-butanol and acetic acid to form water and n-butyl acetate‚ and to confirm the esterification using IR spectroscopy analysis. It was found that 0.734 grams of n-butyl acetate was formed with a percent yield of 61%. The product was confirmed using IR spectroscopy and boiling point confirmation. The reaction mechanism

Conclusion Teen pregnancy is a pregnancy in female human-beings who are below the age of twenty years and being a teen parent it isn’t as great as it sounds. Teen pregnancy should be highly discouraged has it has effect on the teenage mother and the baby born. The teen mother may face complications such as premature labor‚ medical complication during the pregnancy period‚ at child birth or after child birth and are likely to drop out of school. One cause for an early pregnancy for a teenager

How Colonialism led to Poverty in Africa The native Africans have been in a state of poverty and have not been able to fix it. They have been trying for centuries to live a decent life‚ but have yet to succeed. The Europeans could have helped the Africans with their situation‚ but instead‚ they tried to colonize their land. As a result‚ some Africans fought while others fell into the dark grips of imperialism. Europeans benefitted greatly while the Africans suffered more than before from poverty

Lab Conclusion on Density In the lab of measuring density‚ precision and accuracy are very key components. Precision is the exactness of a measurement or good technique. Now accuracy is the value that we measured compared to the true value that the book has. Precision and accuracy are important because you need to have good technique and have your value close to the true value to minimize the error analysis. If you do these steps correctly you are a good chemist but if you do them poorly they
