Answer 2

Answer:

The metal X is copper. Copper on being heated in the presence of oxygen forms copper oxide which is basic in nature and black in colour. The chemical equation for the above reaction is as follows

Heat

2Cu+O - - - - - 2CuO

2

If hydrogen gas is passed over this black coating that is CuO, the black coating turns brown as the reverse reaction takes place and copper is obtained back. The chemical equation for this reaction is as follows

Heat

CuO+H - - - - - Cu+H O

Thus, substance X is copper (Cu) and Y is copper oxide (CuO).
