Question

Select the correct answer.

Which products are formed during the decomposition of magnesium nitride (Mg3N2)?

A.
Mg + 3N2
B.
3Mg + 2N2
C.
Mg + 3N
D.
3Mg + N2
E.
2Mg + 3N

Answer 1

Answer:

D. 3Mg + N2

Explanation:

magnesium nitride will decompose to form elemental magnesium and nitrogen gas

Mg₃N₂  → Mg + N₂

The reaction now needs to be balanced So that the number of Mg and N atoms in the reactants is equal to that of the products
