Experiment E: Post lab Natasha Buckiewicz (130361780) IA: Matt Halloran Due: November 26‚ 2014 1. This experiment followed GCP number 8 which is reduce derivatives. This experiment did not use unnecessary derivation since the reaction was not modified in any way. No additional reagents were required so it did not generate a lot of waste. 2. Safer solvents and auxilaries (GCP #5) was not used in this experiment since the experiment used a solvent to complete the reaction. The reaction used both

A river boat can travel at 20km per hour in still water. The boat travels 30km upstream against the current then turns around and travels the same distance back with the current. IF the total trip took 7.5 hours‚ what is the speed of the current? Solve this question algebraically. Let x = speed of current Upstream speed=20+x Downstream speed=20-x =) 30/20-x + 30/20+x = 7/5 =) (20-x)(20+x) = 400-x^2 =) 30(20-x)+30(20+x)=7.5(400-x^2) =) 600-30x+600+30x=3000-7.5x^2 =) 7.5x^2 = 3000-1200

Chemical Reaction is a process that involves rearrangement of the molecular or ionic structure of a substance‚ as opposed to a change in physical form or a nuclear reaction. Reactant is a substance participating in a chemical reaction‚ especially a directly reacting substance present at the initiation of the reaction. A word equation is an equation where only the words of the products and reactants are given. It is used to describe chemical reactions using words. A skeletal equation is a chemical

Tonsilloliths or tonsil stones are small groups of calcerous substances at the back of the mouth. These stones are specifically found on the tonsillar crypts of the tonsils. They are white small bumps in the throat; sometimes white-yellowish in color. The tonsil stones appear harmless‚ except that they can in your social life because they can really make your breath smell bad. Thus‚ you would want to remove tonsil stones using effective treatments. In treating tonsil stones‚ you actually have many

74. b) Select one example of a physical change from your table‚ and explain why it has a physical change. Step number one where “A coarse screen made of metal bars filters large particles and trash‚ such as bottles and cans.” This would be considered a physical change because there is no chemical process taking place. As well you are able to see a physical change in the water due to trash and debris being filtered out by nothing more then a screen. This screen is doing nothing more other then
