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

“Correlation doesn’t equal causation” Albert Einstein once said “The world is in greater peril from those who tolerate or encourage evil than from those who actually commit it.” At this point in my life‚ I couldn’t have found that statement to be any truer. I’m an activist‚ an avid one at that. I try to fight evil educating others‚ on what not many people have ever even questioned before; Vaccines. When I tell most people this‚ their first reaction is “oh‚ you’re one of those people” or “I get it

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.

natural convection. Forced convection is due to a large interfering flow of air such as a fan. Aims and objectives The aim of this laboratory experiment it to find the convection heat transfer coefficient of a flow of air that is flowing over a heated plate at a known speed. The convection heat transfer coefficient can be determined using the values of temperatures recorded‚ the area of the heated plate and finally the energy converted into heat. The main objective of this laboratory is to prove the

“Why Draw” by Tim Parsley provides clarity on the unanswered question of technique alone creating a project and that drawing is a journey of self-discovery. Parsley draws attention to the fact that drawing takes patience. Through this moment of focus and meditation we can better understand ourselves and the world around us. We “see.” The author reflects on a story about one of his students. She asks how to draw a nose. This question is similar to many other complicated answers in this world. How

VI- CONCLUSION The eye is the organ of vision. It has a complex structure consisting of a transparent lens that focuses light on the retina. The retina is covered with two basic types of light-sensitive cells-rods and cones. The cone cells are sensitive to color and are located in the part of the retina called the fovea‚ where the light is focused by the lens. The rod cells are not sensitive to color‚ but have greater sensitivity to light than the cone cells. These cells are located around the
