Rachel Rodriguez Anthony Chirumbolo December 8, 2011 Chemistry I, Pd 11, Station K Evidence of Chemical Change Purpose To observe several chemical changes (reactions) and the evidence they exhibit for chemical change. Data See page 3 Analysis The two terms that describe possible energy change in a chemical reaction are Exothermic, for example when a gas is formed when Copper II Chloride and Aluminum are mixed, and Endothermic, for example when copper II Hydroxide is heated. There are many substances used in this experiment, the elements are Hydrogen Gas, Aluminum, and solid Copper, the compounds are Copper II Nitrate, Sodium Hydroxide, Copper II Hydroxide, Copper II Oxide, Hydrochloric Acid, Sodium Nitrate,
