Once the aspirin is prepared‚ it is isolated from the reaction solution and then it is purified. The aspirin is insoluble in cold water‚ and it is isolated by filtering the chilled reaction solution. Purification is essential to remove any unreacted salicylic acid and acetic anhydride as well as the acetic acid product and phosphoric acid. Acetic anhydride is caused to decompose by the addition of water once the formation of aspirin is complete. C4H6O3 (Acetic anhydride) + H2O (Water) ------------------------->

"Fences" and "The Piano Lesson" are two extraordinary works created by August Wilson. Throughout these two plays there is a constant struggle while at the same time these stories revolve around a similar theme or symbol.

Contrasts of Troy and the Iliad Troy and the Iliad are very similar in the story line and the all-around theme but there are huge fundamental changes the director made to the story to increase the likeability of the movie. Troy includes some of the significant events from the Iliad but there are extremely important events of the book that he did not include and some events that are important to the movie that never actually happened in the book. The three most important fundamental changes of the

This was not an idea forced onto the people of the time‚ it was something ingrained in Roman culture. At the fall of Troy Aeneas‚ the son of Venus‚ was instructed to go and found a new empire. His destiny could not be stopped by romance or even his own family. Aeneas was fated to not only found Rome‚ but bring values to the soon-to-be empire. As the city around him
