Write the skeletal equation for the following reactions :(i) Hydrogen suiphide reacts with sulphur dioxide to form sulphur and water.(ii) Methane on burning combines with oxygen to produce carbon dioxide and water.What is the need of balance equations ?

Answer»

(i) 4H2S + 2SO2 → 6S + 4H2O

(ii) CH4 + 2O2 → CO2 + 2H2O

To obey the law of conservation of mass; so that the number of atoms of each element before and after the reaction remain the same.
