The goals of this experiment are to determine if the products derived from amide synthesis and Williamson Ether Synthesis are identical‚ and if one of the synthetic routes is more advantageous than the other. In Part 1‚ an attempt to synthesize acteophenetidin crystals by amide synthesis was made. We began by removing the colored impurities from the p-Phenetidine (reddish-brown) by placing 2g of the sample in 38 mL of hydrochloric acid and heating the solution to boiling point. Upon reaching just

The Sun It’s crazy to think that the big ball of fire that we looked at through a telescope in the beginning of the semester used to be nothing more than a cloud of gas and dust. I mean this is the center of our universe and greatest source of energy we are talking about and it was just basically a bunch of tiny particles floating in space trying to find their place in the universe. It wasn’t till gravity hit that these particles started fusing together. As a result a star was born and began to

The Sun The sun is the largest object in the solar system. It is a middle-sized star and there are many other stars out in the universe just like it. Even though it is only a middle-sized star it is large enough to hold over 1 million Earth ’s inside if it were hollow. The temperature on the sun is far too much for any living thing to bear. On the surface it is 10‚000 degrees Fahrenheit and the core is a stunning 27‚000‚000 degrees Fahrenheit. But don ’t worry we are over 90‚000 million

Social scientists have studied it‚ lawyers have tried to fix it and post-feminist society is over it. But women are still outnumbered by men in math‚ science and engineering fields. Most overt discrimination against women in the sciences has been reduced or eliminated in recent decades through legal‚ academic‚ corporate and government measures. But a climate that is less than fully friendly to women remains‚ and its texture is often still so taken for granted that it tends to be invisible. The
