Rusting is a chemical reaction where iron is slowly broken down when exposed to water and air. It is categorized as an oxidation reaction; oxygen, water and iron react to form hydrated iron (III) oxide, which is known as... More »

Rusting is the process in which iron turns into iron oxide. It happens when iron comes into contact with water and oxygen. The process is a type of corrosion that occurs easily under natural conditions. More »

No, the rusting of iron is a chemical change because it is two substances reacting together to make a new substance. When iron rusts, iron molecules react with oxygen molecules to make a compound called iron oxide. Rusti... More »
