Nitration and Purification of Bromobenzene Abstract: An electrophilic aromatic substitution reaction was performed on bromobenzene with nitric acid producing both 2-bromonitrobenzene and 4-bromonitrobenzene. Products of the reaction were purified through multiple recrystallizations and column chromatography creating multiple crops of a yellow powder. The percent yield of products was determined to be 51%. The melting point of Crop 1 was found to be 110-115 °C‚ and Crop 2 was found to be 37-90

Study of Water Purification Methods Water is the most essential component of life on Earth. In the United States‚ the average person uses about 75 gallons per day of freshwater. Most of this water is pre-treated in facilities and comes out of the tap clean and ready for drinking‚ a fact many take for granted. If you are camping and hiking you won’t always have access to this source of healthy‚ potable water. Unfortunately‚ many water sources in the wilderness include microorganisms‚ bacteria

50/50 50/50 was such a spontaneous movie to have seen‚ even though it had “simple” scenes in it and a basic plot of a “basic tragedy” life story of a man who finds out that he has cancer. But it’s not just about a man with cancer and how he accepts his short cut of his life and died. No. This movie was more than just that‚ actually‚ the movie showed the man with cancer more than just a man who has cancer‚ which is why it made it interesting for me. This man did have a simple ordinary life yet;
