Examples of Chemical Properties

Chemical properties are characteristics of a material that become evident when the material undergoes a chemical reaction or chemical change. People cannot observe chemical properties by simply viewing or touching a sample of the material; the actual structure of the material must be changed in order for people to observe the chemical properties.
