The response that demonstrates a chemical change is:
Iron (Fe) reacting to water (H2O) and oxygen (O) to form iron oxide (Fe2O3).
This process involves a chemical reaction where iron combines with water and oxygen to create a new substance, iron oxide (rust). The other options listed are physical changes.
