More Information
Rusting is classified as a chemical change because it involves the reaction of iron with oxygen to form iron oxide, which is a new substance. This process alters the chemical properties and composition of the original material.
Tips
A common mistake is assuming rusting is a physical change because it involves a visible transformation of matter. However, physical changes do not alter the chemical composition of the material.
