The rusting of iron is clearly an example of chemical change.

Explanation:

Chemical change is characterized by the formation of new substances and the making and breaking of strong chemical bonds. In these circumstances we break iron-iron bonds and oxygen-oxygen bonds, and form #Fe^(II)O# and #Fe^(III)O# bonds. See this older answer.
