the equation below shows lithium reacting with nitrogen to produce lithium nitride.\n6li + n₂ → 2li₃n\nif 12 mol of lithium were reacted with excess nitrogen gas, how many moles of lithium nitride would be produced?\n4.0 mol\n6.0 mol\n12 mol\n36 mol
Answer
Explanation:
Step1: Analyze the mole ratio
From the balanced equation (6\text{Li}+\text{N}_2\rightarrow2\text{Li}_3\text{N}), the mole ratio of (\text{Li}) to (\text{Li}_3\text{N}) is (6:2 = 3:1).
Step2: Calculate the moles of lithium nitride
Let (x) be the moles of (\text{Li}_3\text{N}). Using the mole ratio (\frac{\text{mol Li}}{\text{mol Li}_3\text{N}}=\frac{3}{1}). Given (\text{mol Li} = 12) mol. Then (x=\frac{12}{3}) mol.
Answer:
A. (4.0) mol
