Metal her surface is made from?

Which metal get green coating whrn exposed to air?

How do you do copper coating on iron powder?
Contacting the iron powder with an aqueous solution of copper (II) salts will produce a copper coating on iron powder: Iron is higher in the electromotive series than copper and therefore will displace copper from the solution, resulting in copper-coated iron and dissolved iron cations. When all of the surface of the iron powder has been coated with copper, the iron will stop reacting because it no longer has access to the copper ions in solution, the access of the iron being blocked by the layer of copper coating the remaining iron powder.
What evidence is there that a chemical reaction occurred on the surface of the statue of liberty?
When a chemical reaction occurs, elements and compounds combine in different ways to make new materials. The elements copper and oxygen have reacted to form a new compound, copper oxide.
