Write the skeletal equation for the following reactions: (i) Hydrogen sulphide reacts with sulphur dioxide to form sulphur and water. (ii) Methane on burning combine with oxygen to produce carbon dioxide and water.

(i) When hydrogen sulphide react with sulphur dioxide, it forms sulphur and water. The skeletal (unbalanced) equation for the reaction is:


H2S + SO2→ S + H2O


(ii) When methane reacts with oxygen, it forms carbon dioxide and water. The skeletal equation for the reaction is:


CH4 + O2→ CO2 + H2O
