Hi guys, I need your help: A white solid V is heated strongly. At a high temperature, V gives off carbon dioxide and changes to a solid W that begins to glow. When water is added to W, it begins to fizz, produces heat and crumbles to a powder X. X dissolves in water to form an alkaline solution Y. When carbon dioxide is passed into solution Y, the solution turns cloudy. The cloudiness is caused by a white suspension Z and its formation is used as a test for carbon dioxide. (a) Deduce the identity of V, W, X, Y and Z, giving either their chemical or common names. (b) Write chemical equations for the action of: (i) heat on V, (ii) carbon dioxide on solution Y. (c) State a use for either W or X. Please help me solve this 2 problems, I really don't know how to do. Thanks.
