Evidence of a chemical reaction includes:. Chemical Reaction. 1) Change in color / light. 2) Change in temperature. Evidence of a chemical reaction includes:. Chemical Reaction. 1) Change in color / light. All. chemical reactions either release or absorb energy. . The energy can take many forms: . HEAT. , . LIGHT. , . SOUND. , and . ELECTRICITY. . Chemical . bonds. are the source of this energy. . Chemical Reactions. Chemical reactions occur every minute of every day. . Some are very fast, such as the reaction of sodium with water. . Others are very slow, such as iron rusting. . Some are somewhere in-between, such as milk going sour. . Nikhil . Gopalkrishnan. (From presentation of Chen, Doty, .
