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%

The case of Zara: a supposed exception to globalization The article written by Nebath Tokatli is about the case of Zara‚ a fast fashion retailer company supposed to be an exception to the global trend of this sector. The author‚ after a brief introduction in which she declares her purpose to demonstrate this idea to be false‚ starts describing the change in the culture of fashion from “houte couture” and ready-to-wear too fast fashion. Fast fashion retailers do not directly invest in design

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

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

on the Spanish retail giant‚ Inditex and how its largest retail chain Zara has been so successful through its simple business model of speed‚ flexibility‚ and high fashion. As of 2002‚ Inditex had six separate chains: Zara‚ Massimo Dutti‚ Pull & Bear‚ Bershka‚ Stradivarius‚ and Oysho. Each chain operates independently and is responsible for its own strategy‚ product design‚ sourcing and manufacturing‚ distribution‚ retail. Zara is by far the largest‚ most profitable‚ and most internationalized of
