A) i) when copper is left exposed to air, it forms a green coat.
ii) The process involved is the reaction of copper with moist air and oxygen. This leads to the turnishing of copper just as the rusting of iron.
b)The green coating is Copper carbonate, sometimes referred to as patina or verdigris.

metal x is copper
the process for this change os corrosion
its reaction is 4Cu+O2->2Cu2O
this is oxidation reaction
it can be prevented by following ways
1 by greasing
2 use copper corrosion inhibitors
