Lab E: Adapted from Experiment #10 TA: Sudipta Biswas Tuesday‚ 1:05pm 10/25/11 Sarah Kempkes Abigail Scherer Abstract: The purpose of this experiment was to create and obtain pure acetaminophen. p-aminophenol and acetic anhydride were used to create acetaminophen and acetic acid. The acetic acid mixed with acetaminophen created an impure sample‚ which was purified through the addition of a water/methanol solution. The percent recovery of acetaminophen from the impure sample to the pure

Film is a different medium through which to convey historical experiences of war and its social and cultural contexts. As learned throughout class‚ memoirs and non-fiction portrayals of war are excellent sources in which to learn of war and its effects on society and vice versa. Film‚ however‚ is no better or worse than these books. Throughout the semester‚ the class learned of the development of modern warfare since the Civil War in the late nineteenth century and the society that surrounded these

Abstract Oxidation was found for primary alcohol. When 6 drops of potassium dichromate and 1 drop of concentrated sulfuric acid were added to 1-pentanol‚ the color of 1-pentaol turned into dark green. In second experiment‚ precipitation was found when 6 drops of 2‚4-dinitrophenylhydrazine were added to both 5 drops of benzaldehyde and 5 drops of acetophenone. Based on these data‚ it is possible to find alcohol by oxidation and aldehyde by observing precipitation Introduction This experiments

Jazz has been called‚ among other things‚ America’s "only original form‚" showing it’s clear cultural roots in America. In addition‚ jazz historians have touted jazz’s pedigree as "American’s Classical Music." An appreciation and analysis of jazz history forces one to question both the "American" and "Classical" descriptors that past historians have used to label jazz music. Using primarily sources such as "From Somewhere in France" by Charles Delaunay and "An Interview with Wynton Marsalis" by Lolis

RESULTS AND DISCUSSION In the Iron (II) - Silver Ions System the reaction had a balance chemical equation of Fe2+ + Ag+ Fe3+ + Ag(S). The process if centrifugation is used in this part of the experiment to be able to separate the supernatant and the precipitate. And the supernatant will be used to test for the presence of Fe2+‚ Ag+ and Fe3+ in the solution. Results showed that there is a positive presence for FE 2+‚ Fe3+ and Ag+ because of the visible change of color of Prussian blue precipitate

The Role of DNA in Protein Synthesis DNA is found in the cells nucleus. It is part of the chromosome of the cell. DNA is the molecule that controls the making of protein. Protein is used for the growth of cells and organisms and also for the repair of cells. Protein is also used as an enzyme to speed up reactions in the body. Because of this DNA is able to control the whole organism. With out DNA and its ability to make protein the cells and eventually the whole organism would die
