When an object or solution changes appearance is it a chemical change?
Not necessarily. When ice melts into water, its appearance changes, since ice is a solid and water is a liquid, but that's a physical change. Both water and ice are H2O, so the chemical composition does not change, making it a physical change and not a chemical change. However, when iron reacts with oxygen to produce rust, its appearance also changes. You end up with iron oxide (a.k.a. rust) which has a different chemical composition than just iron and just oxygen. That's a chemical change. If you end up with something new that you didn't have before, it's a chemical change.
