The option that demonstrates a chemical change is:
Iron (Fe) reacting to water (H₂O) and oxygen (O) to form iron oxide (Fe₂O₃).
This reaction involves the transformation of iron and other substances into a new compound (iron oxide), which is a characteristic of a chemical change. The other options involve physical changes rather than chemical changes.
