Explain why ammonia is evolved when water is added to magnesium nitride

Asked by lovemaan5500 | 21st Oct, 2017, 04:41: PM

Expert Answer:

Magnesium nitride reacts with water to produce magnesium hydroxide and ammonia gas, like do many metal nitrides.

Nitrogen get combined with hydrogen from water molecules to form ammoina gas.

The balanced reacion is as follows:
 
Mg3N2(s) + 6H2O(l) → 3Mg(OH)2(aq) + 2NH3(g)
