Automotive air bags inflate when sodium azide decomposes explosively to its constituent elements:

Question

Question

2NaN₃(s) → 2Na(s)+3N₂(g)

How many moles of N₂ are produced by the decomposition of 3.55 mol of sodium azide?

Answer 1

✔ Recommended Answer

Answer #1

Let x be the number of moles of N2 produced

2 moles of NaN3 gives-------> 3 moles of N2

3.55 moles of NaN3 gives-----> x

Cross multiply

2X=3*3.55

X= 5.325 moles = 5.33 mol
