Rusting is a chemical change, as steel/iron turns into iron oxide.
Is a tin can rusts a physical or chemical change?
Yes, it is, because the chemical composition of the outside changes due to oxydation.
is iron rusts a chemical or physical change?
The rusting of iron is a chemical change. It involves the reaction of iron with oxygen in the presence of moisture to form iron oxide (rust), which has different chemical properties compared to the original iron.
When iron rusting is an example of a what change?
When iron rusts, it undergoes a chemical change. This is because the iron reacts with oxygen in the air to form iron oxide, which has different chemical properties compared to the original iron.
Is iron that rusts in moist a physical property chemical property physical change or a chemical change?
Rusting is a chemical process, an oxidation reaction.
Why the exposed metal rusts is a chemical change?
Assuming the metal is ferrous(contains iron) then rusting represents a chemical change because the metal (in the presence of water and oxygen) is changed into a different compound, Fe2O3. Since we started with an iron containing metal and we now have Fe2O3 which is not the same substance, a chemical change must have occurred.
Is metal chair-rusts physical or chemical change?
The rusting of a metal chair is a chemical change. The iron is undergoing oxidation as it combines with oxygen to form iron oxide.
