purpose of this experiment is to synthesize methyl nitrobenzoate from methyl benzoate‚ concentrated HNO3‚ and concentrated H2SO4 via an electrophilic aromatic substitution reaction. Reaction Procedures/ Observations Use a 50 ml beaker to cool about 6 ml of concentrated sulfuric acid in an ice water bath. Weigh the vial containing about 3 grams of methyl benzoate and add it to the cooled sulfuric acid. Next pour about 2 ml of sulfuric acid to the nitric acid in the vial and allow for it to cool

"A man who cannot choose ceases to be a man."Anthony Burgess A Clockwork Orange is a novel about moral choice and free will. Alex ’s story shows what happens when an individual ’s right to choose is robbed for the good of society. The first and last chapters place Alex in more or less the same physical situation but his ability to exercise free will leads him to diametrically opposite choicesgood versus evil. The phrase‚ "what ’s it going to be then‚ eh?‚" echoes throughout the book; only

An Unknown Amino Acid From Titration Abstract Experiment 11 used a titration curve to determine the identity of an unknown amino acid. The initial pH of the solution was 1.96‚ and the pKa’s found experimentally were 2.0‚ 4.0‚ and 9.85. The accepted pKa values were found to be 2.10‚ 4.07‚ and 9.47. The molecular weight was calculated to be 176.3 while the accepted value was found to be 183.5. The identity of the unknown amino acid was established to be glutamic acid‚ hydrochloride. Introduction

is a little Alex in all of us” In Anthony Burgess’s Clockwork Orange one important question keeps popping up throughout the whole book. The question is does goodness exist in this novel? “Burgess novel is troubling and frustrating on a number of levels. He has presented us with a stark image of evil‚ and perhaps of a greater evil in attempting to counteract it” (Newman 68). I would have to say that no one in the novel is good. From beginning to end; page after page in one way or another someone

The Purity and Purification of Solids Recrystallization ABSTRACT In this experiment‚ impure adipic acid is purified though recrystallization. The impure adipic acid is dissolved in a solvent. After cooling it is ran through a vacuum filter to separate any moisture. The dry crystals are then weight for percent yield and the melting point range is taken to test the purity. There were two different trials ran in this experiment. The difference between the two was the addition of charcoal in
