Automotive air bags inflate when sodium azide decomposes explosively to its constituent elements:
2NaN₃(s) → 2Na(s) + 3N₂(g)
How many moles of N₂ are produced by the decomposition of 2.88 mol of sodium azide?

Question

Quizplus · Accepted Answer

According to the balanced equation, 2 moles of sodium azide produce 3 moles of N₂. Therefore, we can use a proportion to find the number of moles produced by 2.88 mol of sodium azide: 2 mol NaN3 / 3 mol N₂ = 2.88 mol NaN3 / x Solving for x gives: x = (3 mol N₂ × 2.88 mol NaN3) / 2 mol NaN3 = 4.32 mol N₂ Therefore, 2.88 mol of sodium azide produces 4.32 mol of N₂, and the answer is (C).
