Answer to Question #347495 in General Chemistry for Daniel Ortiz

Question

Automotive airbags inflate when sodium azide decomposes explosively to its constituent elements. How many moles of NA are produced by the decomposition of 1.75 mol of sodium azide

Answer 1

2 NaN₃(s) → 2 Na(s) + 3 N₂(g)

From the equation above, Sodium azide has a chemical formula of NaN₃ while nitrogen gas has a chemical formula of N₂.

Therefore, If on decomposition

2 moles of NaN₃ produce 3 moles of N₂

1.75 mol of NaN₃ produce X moles of N₂

X = 1,75 * 3 / 2 = 2.625 mol

ANSWER: 2,625 mol
