9/19/2012 Experiment #1-Density Aim: Learn how the process of distillation occurs. Observe how distillation separates alcohol from wine. Method: Distillation is based on the fact that the matter can exist in three phases - - solid‚ liquid and gas. As the temperature of a pure substance is increased‚ it passes through these phases‚ making a transition at a specific temperature from solid to liquid (melting point--mp) and then at a higher temperature from liquid to gas (boiling point--bp). Distillation

August 22‚ 2013 Assignment 1: The Chemistry of Life Effects of Acid Rain There are many different types of negative effects acid rain has on the world. Acid rain is the mixture of wet and dry deposition from the atmosphere containing higher than normal amounts of nitric and sulfuric acids. Pollution contributes to the forming of acid rain. One of the main causes is industrial burning of coal and other fossil fuels the oxides they contain and combine with atmospheric water which forms acids.
