What type of chemical change is rusting of iron?
Answer and explanation
Correct answer: Slow oxidation
Rusting occurs when iron reacts slowly with oxygen in the presence of moisture, producing hydrated iron(III) oxide. Oxygen is added to iron, so the process is oxidation; because it develops gradually rather than suddenly, it is specifically slow oxidation and option A is correct. The other choices describe physical changes, not rust formation.
