Answer:
The formation of rust requires iron, water and oxygen. Although it's a complex process, the chemical equation is simply 4Fe + 3O2 + 6H2O → 4Fe(OH)3.
2).The rusting of iron can be prevented by painting, oiling, greasing or varnishing its surface. (b) Galvanisation is another method of protecting iron from rusting by coating it with a thin layer of zinc.
