rusting is oxidation, so it is definitely a chemical change
Sanding rust off a bike is a physical change because it does not alter the chemical composition of the rust or the metal underneath. It only changes the physical appearance by removing the rust layer mechanically through abrasion.
When it combines with Oxygen. Commonly called Rust.
Examples: Iron Rusting: CHEMICAL CHANGE The ABILITY for Iron to rust: Chemical PROPERTY Ice freezing: Physical CHANGE Water's ABILITY to evaporate: Physical PROPERTY
No. It is chemical change because that rust will never be a metal again. A chemical change is a change that is irreversible. ( Ex. Your rake ( that rust will never be a metal again.) A physical change is a change that still has the same compound. Ex. sand ( rocks, just littler.)
Rusting iron is a chemical change because it involves a chemical reaction between iron, oxygen, and water to form iron oxide (rust). This process cannot be easily reversed by physical means.
Chemical change.
