Question

would rust forming on a boke be a chemical reaction or physical reaction

Answer 1

Rust forming on a metal object, such as a bike, is primarily a chemical reaction. It occurs when iron in the presence of oxygen and moisture undergoes oxidation, resulting in the formation of iron oxide (rust). This process involves the breaking and forming of chemical bonds, which categorizes it as a chemical reaction rather than a physical one. Physical reactions typically involve changes in state or appearance without altering the chemical composition of the substances involved.
