A magnesium ribbon is burnt in oxygen to give a white compound X accompanied by emission of light, If the burning ribbon is now placed in an atmosphere of nitrogen, it continues to burn and forms a compound Y.
(a) Write the chemical formulae of X and Y.
(b) Write a balanced equation when X is dissolved in water.

The burning of magnesium ribbon is an example of a combination reaction.
When magnesium burns in the presence of oxygen, the reaction is given as:
2Mg + O2 → 2MgO
When magnesium burns in the presence of nitrogen, the reaction is given as:
3Mg + N2 → Mg3N2
The chemical formulae of X and Y are MgO [Magnesium Oxide] and Mg₃N₂ [Magnesium nitride] respectively.
If Magnesium Oxide is dissolved in water, the product is Magnesium Hydroxide
MgO + H2O → Mg(OH)2
