Why does Mg3N2 form in insufficient air?

Answer 1

Magnesium nitride (Mg3N2) is formed by the reaction of magnesium metal (Mg) with nitrogen gas (N2).

Answer 2

Mg3N2 forms in insufficient air because magnesium reacts with nitrogen gas to form magnesium nitride. When there is not enough oxygen present, magnesium is more likely to react with nitrogen to form Mg3N2 rather than magnesium oxide (MgO).

Answer 3

Mg would preferentially form MgO but if there is not enough O2 in the air, it will form Mg3N2 instead

Answer 4

The reaction equation is.

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

The products are magnesium oxide and ammonia.

Answer 5

Mg3N2 is a compound, not an element. It is magnesium nitride.
