Answer 1

The process that is an example of a chemical reaction is **rusting**. Rusting involves the chemical reaction of iron with oxygen in the presence of moisture, resulting in the formation of iron oxide (rust). The other options — freezing, boiling, and melting — are physical changes, not chemical reactions.
