Explanation / Answer

I think that there is a mistake.

It should be nitrogen gas instead of oxygen gas.

Magnesium nitride undergoes thermal decomposition reaction to form magnesium metal and nitrogen gas. Reaction is as follows:

Mg3N2 --- 3Mg + N2.

The above reaction occurs around temperature 700- 1500 C

If Magnesium nitride reacts with water and undergoes thermal decomposition then ammonia and magnesium oxide forms. or ammonia and magnesium hydroxide forms

The reaction is:

Mg3N2 + 3H2O --- 2NH3 + 3MgO
