. 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 chemical equation, when X is dissolved in water.

Best Answer

Answer: 2Mg + O₂ →2MgO

Compound X→ MgO  [ Magnesium Oxide ]
 
Compound Y →Mg₃N₂  [ Magnesium Nitride ]
 
If Magnesium Oxide is dissolved in water, the product is Magnesium Hydroxide
 
MgO  + H₂O → Mg(OH)₂
