A certain compound X impats golden yellow flame. Whenzinc powder is heated with concenrated solution of X, H_(2) gas is evolved. X combines with CO_(2) to give a salt Y. Y is a hydrated salt which on reaction with HCl or ecess of CO_(2) gives another salt Z which is an important part of baking powder. identify X, Y and Z.
