On passing 3 faradays of electricity through three electrolytic cells connect in series containing Ag+ , Ca+2 and Al+3 ions respectively , the molar ratio in which three metals ions are liberated at the electrode is

We are find molar ratio of metal ions by applying faraday's first law of electrolysis

1 ml of gaseous aliphatic compound CxHyOz is completely burnt in an excess of O2 and cooled to room temperature. The contraction in volume is..

Contraction of volume is volume of gaseous mixture taken minus , volume of gaseous products obtained in a combustion reaction. In combustion of Hydrocarbon water obtained at room temperature is in liquid state hence it's volume ignored in calculation of volume contraction.

Why Lithium is store in paraffin wax, not in kerosene oil unlike other alkali metals?

Lithium metal has low density and is a light metal than other alkali metal and therefore floats on the surface of the kerosene oil. To prevent its contact with air, it is wrapped in paraffin wax.
