The option that demonstrates a chemical change is:
**iron (Fe) reacting to water (H2O) and oxygen (O) to form iron oxide (Fe2O3)**.
In this process, a chemical reaction occurs, resulting in the formation of a new substance (iron oxide), which is indicative of a chemical change. The other options describe physical changes.
