The response that demonstrates a chemical change is:
**iron (Fe) reacting to water (H2O) and oxygen (O) to form iron oxide (Fe2O3)**.
This process is a chemical reaction where new substances (iron oxide) are formed. The other options either represent physical changes (like dry ice vaporizing, steam condensing, or sugar dissolving in water) rather than chemical changes.
