The response that demonstrates a chemical change is:
iron (Fe) reacting to water (H₂O) and oxygen (O) to form iron oxide (Fe₂O₃)
This reaction involves the formation of a new substance (iron oxide) through a chemical reaction. The other options involve physical changes (like vaporization, condensation, and mixing) rather than chemical changes.
