A solid 'X' when heated evolves a colourless gas which does not support combustion. The residue is dissolved in water to form 'Y' which can be used during construction and white washing. When excess carbon dioxide is bubbled through the solution of 'Y' , compound 'Z' is formed. When 'Z' is heated gently, 'X' is reformed. Identify 'X' and discuss the reactions.
