The option that demonstrates a chemical change is:
**iron (Fe) reacting to water (H2O) and oxygen (O) to form iron oxide (Fe2O3).**
This is a chemical change because it involves a reaction that transforms the iron into a different substance, iron oxide. The other options describe physical changes rather than chemical changes.
**iron (Fe) reacting to water (H2O) and oxygen (O) to form iron oxide (Fe2O3).**
