Answer 1

as the problem we have two coins one is silver and another one is copper the reactions are as follows :

1)when copper reacts with oxygen

cu2+o2.......2cuo2

here the corrosion property is occurs copper reacts with atmosphere as oxygen.and it will be reversible

2)silver reacts with oxygen

2Ag+o2........2Ag2o.....

here also corrosion occurring the oxidation is occurs...

Answer 2

Cu + O2 = 2CuO2. Copper oxide.

2Ag + O2 = 2Ag2O. Silver Oxide.
