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%

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

The leadership strengths and weaknesses of John Smith evoked a profound effect on the Jamestown colony. The fact that Smith actually arrived in the colony as a common prisoner and was able to achieve the leadership role that he gained is amazing. His creativity and knowledge in certain areas actually saved the colonists from attack and starvation in the early days. Some of the rules he enforced as a leader were actually instrumental in saving the colony. His skill in dealing with the natives

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

Rethinking Jamestown Sheler‚ Jeffery L. The article Rethinking Jamestown was written by Jeffery Sheler in January 2005 the article is about the Archaeological finds of the original fort built in 1607-1620. The author goes in depth of what artifacts were found‚ and when the artifacts were used. It also references how Jamestown was formed‚ and other facts about Jamestown the original fort. The author backs up his thesis with facts found in the archaeological finds of Jamestown along with historic

Conclusion: As we have learned from all the information presented to us in the communication world‚ there are many choices out there to relay tidbits of talk‚ video‚ emails‚ text‚ global connection via MySpace or Facebook‚ and face to face communication via webcam; it all just depends on how you (as a user) chooses to use the outlet. All the communication we have investigated has to do with mostly snippets of information‚ like a text through Twitter‚ or a blurp on Facebook; these are not communication
