Question

Do you think formation of rust from iron is a chemical change

Answer 1

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.

Yes,
Formation of Rust from Iron is a chemical change as it leads to the formation of a new substance from two different substances.

Fe + O2 ———> Fe2O3[Rust]
