Question

give the chemical equation of corrosion of copper,iron and silver

Answer 1

When copper or silver combines with oxygen, the process is known as corrosion or oxidation. ... 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.

Answer 2

corrosion . Fe2O3.Xh20

copper. cu

iron. Fe

silver..Ag.
