Automotive air bags inflate when sodium azide decomposes explosively to its constituent elements: 2NaN₃ (s) → 2Na (s) + 3N₂ (g)
How many moles of N₂are produced by the decomposition of 1.75 mol of sodium azide?

Question

Quizplus · Accepted Answer

From the balanced equation, we can see that 2 moles of NaN₃ produce 3 moles of N₂. Therefore, for 1.75 mol of NaN₃, we can calculate the moles of N₂ produced as: 1.75 mol NaN₃ x (3 mol N₂/2 mol NaN₃) = 2.63 mol N₂ The answer is (C) 2.63.
