Chem4Kids: Reactions: Overview

Chemical bonds are made or broken in order to create a new molecule. One example of a chemical reaction is the rusting of a steel garbage can. That rusting happens because the iron (Fe) in the metal combines with oxygen (O 2) in the atmosphere. Chemical bonds are created and destroyed to finally make iron oxide (Fe 2 O 3).
