Answer:

oxidation reaction

Explanation:

Rusting is the oxidation of iron in the presence of air and moisture. Rusting in a chemical change in which iron combines with oxygen to form iron oxide. The molar mass of iron oxide is greater than iron. So the mass of an object after rusting is greater than its initial mass.
