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

The Literature about the Titanic The Titanic sunk April 14‚ 1912 after crashing into an iceberg. More than 1‚500 lives were lost. The sinking of the Titanic made a great impact in history. It was thought to be the fastest ship and to be unsinkable. Although the sinking of the Titanic was so long ago‚ lots of literature has been written about the ship. Three pieces of literature are a poem by David R. Slavitt entitled "Titanic"‚ a folk song published by Carl Sandburg in a book named The America

“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. Higher education is a privilege that I would not take for granted. Although I have only attended college for two years‚ I have expanded my

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

Synopsis: The main aim of the experiment is to find out the amount of calcium carbonate in toothpaste through back titration since calcium carbonate does not dissolve in water. A roughly weighed amount of calcium carbonate is mixed with hydrochloric acid and then titrated against sodium hydroxide. When the indicator turns from pink to orange‚ the volume of sodium hydroxide used is taken down. After doing some calculations‚ the average percentage of calcium carbonate in toothpaste is 19.2%. This average

More Black Children Die in Chicago from Gun Violence than Soldiers from Chicago Die in Iraq By Phillip Jackson Recently in Chicago‚ teen gunman boarded a crowded public bus near a high school and opened fire with a handgun. I imagined this scene must have been similar to the bus bombings that are so common in war-torn Iraq. As I researched this analogy‚ I found striking similarities between what is happening in Black communities across the United States and what is happening in a full-fledged
