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.

i. Write the chemical formulae of X and Y.
ii. Write a balanced chemical equation, when X is dissolved in water.
 
Magnesium ribbon burns in oxygen to form .
 
2Mg + O_2 ​→ 2MgO
 
Burning magnesium ribbon reacts with nitrogen to form .
 
3Mg + N_2 ​→ Mg_3​N_2

Therefore, the formula of X is MgO and Y is Mg_3​N_2.
 
We already know X is MgO. It dissolved in water to form magnesium hydroxide.The balanced chemical equation for this reaction is ​.
