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.
Is iron rusts a physical or chemical reaction?
Iron rusting is a chemical change.
Is iron nail rusts in water a chemical change or a physical change?
Chemical change, oxygen binds with 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.
Is metal still a metal after it rusts?
There is only one metal that rusts and that is iron and its alloys such as steel. All other metals corrode. No, iron is not iron after it rusts. It is now called iron oxide and will disintegrate if left unchecked . That is why we paint our gates with Blackstar Rust Converter and most electronics are coated with gold or a green varnish to prevent reaction with the air.

Is copper turning green in the air physical change?
The reason that copper turns green is the same reason the metal rusts, oxidization. Both metal and copper oxidize when exposed to oxygen and this is a natural process. Copper that is exposed to the outside environment is more likely to turn green and that is why copper vases and decorative pieces in gardens are often green. Copper is a metal that does not react with water (H2O), but the oxygen of the air will react slowly at room temperature to form a layer of brown-black copper oxide on copper metal which looks like green sometimes...
Which metal rusts first copper or iron?
Iron rusts first because it is more reactive than copper. When iron comes into contact with oxygen and water, a chemical reaction occurs that forms rust, whereas copper does not rust easily due to its lower reactivity.
How can you tell there is a chemical reaction when iron rusts?
Because it is not a physical change it is a chemical change.
Is metal chair-rusts physical or chemical change?
