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

Text Solution

Verified by Experts

(i) `4H_(2)S+2SO_(2)rarr6S+4H_(2)O`
(ii) `CH_(4)+2O_(2)rarrCO_(2)+2HO`
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.
