Final answer:
The reaction of lithium nitride with water produces ammonia and lithium hydroxide, corresponding to Answer C.
Step-by-step explanation:
When lithium nitride (Li3N) reacts with water (H2O), the products formed are ammonia (NH3) and lithium hydroxide (LiOH). This reaction occurs because the nitride ion in lithium nitride is a much stronger base than the hydroxide ion, thus readily reacting with water to generate ammonia. The balanced chemical equation for this reaction is:
Li3N + 3H2O → 3LiOH + NH3
Therefore, the correct answer to what is the product formed when lithium nitride reacts with water is Answer C: Ammonia and lithium hydroxide.
