Answer 1

The iron reacts with water and oxygen to form hydrated iron(III) oxide, which we see as rust. Iron and steel rust when they come into contact with water and oxygen – both are needed for rusting to occur. Boiling the water removes the oxygen and the layer of oil prevents it from re-entering.

Sulphur+oxygen = SO2

Answer 2

Explanation:

1)Fe + O2 + H2O ----> Fe + H2O3

2)S + O2 ---->S2O
