An aqueous solution of a gas (X) gives the following reactions :
(i) It decolourizes an acified `K_(2)Cr_(2)O_(7)`.
(ii) On boiling with `H_(2)O_(2)`, cooling it and then adding an aqueous solution of `BaCI_(2)`, a precipitate insoluble in dilute HCI is obtained.
(iii) On passing `H_(2)S` gas in the solution, white turbidity is obtained. identify (X) and give equations for steps (i), (ii) and (iii).
