Question

Why is rusting car a chemical change

Answer 1

Rusting of a car is considered a chemical change because it involves a chemical reaction between the iron in the car's body and oxygen in the presence of moisture. This reaction results in the formation of iron oxide, commonly known as rust. The composition of the metal changes during this process, converting iron into a different compound. Additionally, rusting is an irreversible process, and the formation of new chemical substances occurs, making it a chemical change rather than a physical change.
