Preparation of an Acetic Acid Ester Abstract: 14.1 g of octyl acetate were synthesized from the esterification process using 20.0 ml of acetic acid and 17.9 g of n-octanol. The theoretical yield was 23.8 g of octyl acetate. The percent yield was 59.2%. The purification of the final ester was confirmed by boiling point (186-199°C) and infrared index (nD=1.419). It was a colorless liquid that had a slight fragrance of orange and indescribable chemicals. The Infrared spectra confirmed ester

“A man who has never gone to school may steal from a freight car; but if he has a university education‚ he may steal the whole railroad.” As said by Theodore Roosevelt. While going to college may not be an attainable opportunity‚ I believe for those that it is reasonable to‚ should take every step towards higher education. For me‚ the decision was an easy one.

Dear diary‚ I was reading one of the latest teenage magazines today. I find them rather interesting and informative because they are full of very compelling articles about role models in sport and culture. in this generation. There was a very amusing article on a singer called Miley Cyrus. She is an interesting character. It is amazing to watch what happens to young celebrities‚ as they get older. Often‚ after many years in the spotlight‚ some celebrities appear to develop a very undesirable image

Michelangelo’s Sogno is a black chalk drawing on unprepared‚ cream-colored paper. Slightly larger than 8 x 12 inches‚ the drawing requires close-hand examination. At the center of the Sogno‚ an idealized male nude perches precariously on an open box filled with masks. His upper torso twists to his left as he leans on a sphere for support. He turns his head in the opposite direction‚ looking upward and over his right shoulder to watch a winged creature descent from above. Considerably smaller

Thermochemistry Laboratory Report Abstract The purposes of these three experiments are to determine the heat capacity of a calorimeter and with that data‚ confirm Hess’s Law and observe enthalpy changes within reactions. By measuring the change in temperature that occurs with the interaction of two different reactants‚ we were able to determine both the calorimeter constant and the change in enthalpy of a given reaction. The results were rather mixed‚ as some numbers more closely resembled the

In this local experiment‚ the goal was to use a polyacrylonitrile (PAN‚ (C3H3N)n) in addition to a chalcogel. This chalcogel is efficient at adsorbing I2 gas. Although just the chalcogel itself isn’t mechanically stable especially if it is to be used in the field for actual radioactive iodine capture. By creating a hybrid substance with the PAN and the chalcogel in a mixture‚ the theory is that they can create a mechanically stable efficient iodine capture method. This experiment did not study the

pace and informality in the English language is on the rise. In places where formal language was once a must‚ informality has taken over‚ and questions are raised over whether formal language still has a place in modern English. However‚ despite changes‚ formal language is still in use and is still expected and considered the most appropriate method of address in many situations. In written and spoken communication‚ formal language has the ability to convey knowledge and provide a sense of occasion
