Automotive air bags inflate when sodium azide decomposes explosively to its constituent elements: 2NaN₃ (s) → 2Na (s) + 3N₂ (g)
How many moles of H₂ are produced by the decomposition of 3.55 mol of sodium azide?

Question

Quizplus · Accepted Answer

According to the balanced equation, 2 moles of NaN₃ produce 3 moles of N₂. Therefore, 3.55 mol of NaN₃ will produce: 3.55 mol NaN₃ x (3 mol N₂/2 mol NaN₃) = 5.33 mol N₂ So, the answer is C) 5.33.
