A magnesium ribbon is burned in oxygen to give a white a compund X with emission of light.If the burning of ribbon is now placed in a atmosphere of nitrogen it continues to burn and it forms Y. Identify X and Y

Expert Answer:
Magnesium ribbon burns in air and forms white Magnesium oxide, MgO (X),
2 Mg(s) + O2(g) → 2 MgO(s)
X
The atmospheric nitrogen is generally inert and the burning of magnesium ribbon provides high temperature, which makes nitrogen gas to react with magnesium and form Magnesium Nitride, Mg3N2, (Y)
3 Mg(s) + N2(g) → Mg3N2(s)
Y
Therefore, X is MgO and Y is Mg3N2.
