Lithium and nitrogen react in a combination reaction to produce lithium nitride:
6 Li(s) + N₂(g) → 2Li₃N(s)
How many moles of lithium are needed to produce 0.60 mol of Li₃N when the reaction is carried out in the presence of excess nitrogen?

Question

Quizplus · Accepted Answer

According to the balanced equation, 6 moles of Li are needed to produce 2 moles of Li₃N. Therefore, to produce 0.60 moles of Li₃N, 1.8 moles of Li are required (0.60 moles Li₃N * 6 moles Li / 2 moles Li₃N = 1.8 moles Li).
