Laws of Chemical Change and Heat Flow

The first lesson provides examples of the Law of Conservation and Mass and the Law of Definite Proportions. Recycling of elements is examined. In lesson two, exothermic and endothermic reactions are demonstrated by an experiment that uses the chemical contents of a pocket warmer and dry ice. The third lesson includes demonstrations of oscillating reactions and clock reactions, as well as interesting though hazardous experiments such as a hydrogen explosion, acetone peroxide explosion, surface polymerization, and silver mirror reaction
