Chemical properties can be recognized only when substances react or do not react chemically with one another,
that is, when they undergo a change in composition.
The following chemical properties can be used to help
identify a substance:
The ability of a substance to rust is a chemical property that involves a substance reacting slowly with
oxygen. The process is called rusting.
The ability to burn involves a substance reacting quickly with oxygen to produce light and heat. This process is called burning.
