Question

predict the products of the decomposition of lithium nitride, li₃n. a li₃ + n b li₃ + n₂ c li + n d li + n₂

Explanation:

Step1: Recall decomposition reaction concept

A decomposition reaction breaks a compound into simpler substances. Lithium nitride ($Li_3N$) will break into its constituent elements, lithium (Li) and nitrogen (N). Nitrogen in its elemental form exists as $N_2$ (diatomic molecule in standard - state).

Step2: Write the decomposition equation

The decomposition of $Li_3N$ is $2Li_3N
ightarrow 6Li + N_2$.

Answer:

D. $Li + N_2$
