WebA chemical change happens when a substance’s chemical identity changes. An example of this is rusting. When an iron nail comes into contact with water and is then exposed to the air, it rusts, forming a brown-red substance. This process changes the chemical composition of the original substance.
WebAt this point, a chemical reaction has occurred. This process is also consistent with the principle of conservation of matter presented in Session 3: atoms and ions can rearrange into different molecules, but they never just disappear. As a result, in a chemical change the total number of particles is not changed.
