GENERAL KNOWLEDGE

Detailed explanation-1: -Rusting is an example of a chemical change.

Detailed explanation-2: -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. Rusting would only be a physical change if iron molecules remained pure iron throughout the process.

Detailed explanation-3: -Rusting iron is a chemical property. In this process, iron reacts with oxygen and combines with the oxygen atoms, forming a new substance that is hydrated iron oxide called rust. Hence, the given statement describes the chemical property.
