When copper or iron combine with oxygen, this process is known as oxidation. Another term is corrosion. These metals, along with aluminum over time corrode and lose strength, conductivity and luster. With iron, reddish flakes form when it rusts. The chemical equation in words is-- iron plus water plus oxygen forms rust. In symbols, it is 4(Fe)+ 6 H2O+ 3 O2 forms 4Fe(0H)3 which is rust. Copper reacting with oxygen will produce copper oxide. The chemical equation is 4Cu+ 02 forms 2Cu20. In other words, copper plus oxygen forms copper oxide.

When copper and iorn come in contact with oxygen this proces is called corrosion.

Reaction for copper: 2Cu + O2 --> 2CuO.

Reaction for Iorn: 4Fe + 3O2 ---> 2Fe2O3.
