An element 'X' having green colour and with seven molecules of water of crystallisation was heated strongly to leave a solid residue Y. This Y reacts with conc. nitric acid to form a nitrate 'Z'. This nitrate reacted with hydrochloric acid to form a chloride 'A'. When hydrogen sulphide was passed into Its aqueous solution a black compound B was precipitated. Identify X, Y, Z, A and B and also give the equation involved.
