Air bags in cars inflate when an electrical spark activates sodium azide (NaN ₃) so that it decomposes to sodium metal and nitrogen gas.In the balanced reaction equation, how many moles of N₂ gas are formed for each mole of NaN₃?

Question

Quizplus · Accepted Answer

The balanced chemical equation for the decomposition of sodium azide (NaN₃) is 2 NaN₃ → 2 Na + 3 N₂. This shows that 3 moles of N₂ gas are produced from 2 moles of NaN₃, which means 1.5 moles of N₂ are produced per mole of NaN₃.
