A reddish brown coloured metal, used in electrical wires, when powdered and heated strongly in an open china dish, its colour turns black. When hydrogen gas is passed over this black substance, it regains its original colour. Based on the above information answer the following questions. (i) Name the metal and the black coloured substance formed. (ii) Write balanced chemical equations for both the reactions
