Give an example of an oxidation reaction that can be a nuisance.

An example of a nuisance, oxygen reacts with iron to form rust. This reaction involves the addition of oxygen, which is not needed.
2Fe(s) + 2H2O(l) + O2 (g)---> 2Fe^+2 (aq) + 4OH- (aq)

Most metals react with oxygen and moisture in the surrounding air to form oxides. As a result of such reactions, the metals gradually deteriorate. This is known as corrosion of metals. Corrosion is on oxidation reaction which reduces the economic importance of metals.
The corrosion of iron is specially known as rusting of iron. It involves the formation of hydrated iron III oxide, a soft layer that breaks off easily from the rest of the metal. The overall redox equation representing rusting is:
Fe(s) + 1/2 O2(aq) + H2O(l)-------> Fe^2+(aq) + 2OH^-(aq)

Rusting of iron is an oxidation reaction that occurs when iron reacts with moisture and oxygen, leading to the formation of rust. This corrosion can weaken structures and requires costly maintenance and repair. Therefore, rusting is considered a nuisance in various industries, affecting the longevity and safety of metal objects.
