Answer:
a. True
Explanation:
Magnesium nitride, Mg₃N, is a binary salt. Upon heating, it decomposes into magnesium metal and nitrogen gas. The unbalanced equation is:
Mg₃N(s) ⇒ Mg(s) + N₂(g)
We can balance it with the trial and error method. First, we will balance N atoms by multiplying Mg₃N by 2.
2 Mg₃N(s) ⇒ Mg(s) + N₂(g)
Then, we get the balanced equation by multiplying Mg by 6.
2 Mg₃N(s) ⇒ 6 Mg(s) + N₂(g)
