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

Question

Quizplus · Accepted Answer

From the balanced equation, we can see that 2 moles of sodium azide produce 3 moles of N₂. Using dimensional analysis: 2.88 mol NaN₃ x (3 mol N₂/2 mol NaN₃) = 4.32 mol N₂ Therefore, the answer is (C) 4.32.
