1.	Sonali was performing a experiment in which metal X which was of reddish brown colour, when heated in the presence of oxygen it forms a black coloured compound Y which was basic in nature. When this is again heated in the presence of hydrogen gas it gives back the substance X. Identify the X and Y?
