Answer 2

a) According to the circumstances mentioned in the question,the metal X is most probably the magnesium (Mg) and the compound Y is most probably the magnesium oxide (MgO).

Chemical reaction :

2Mg + O2 = 2MgO

In this above reaction the oxygen is added from the atmosphere which is mandatory for any kind of combustion (burning) reactions.
