A metal 'X' reacts with oxygen to form metal oxide 'Y' which is used for drying NH3. 'Y' dissolves in water producing 'Z' with hissing sound which is used for white washing. The clear solution of 'Z' reacts with CO2 to form white precipitate. Identify 'X','Y' and 'Z' . What is the chemical reaction involved.
