Question

formula for crossion of copper​

Answer 1

When copper reacts with oxygen, then it produces copper oxide. The chemical equation of this reaction is 4Cu + O2 = 2Cu2O, and forms Copper Oxide.

Answer 2

When copper reacts with oxygen, then it produces copper oxide. The chemical equation of this reaction is 4Cu + O2 = 2Cu2O, and forms Copper Oxide. Silver objects corrode slowly in the air due to the presence of H2S in the air. The chemical equation of this reaction is 2Ag + O2 = Ag2O.
