Automobile air bags inflate following a serious impact. The impact triggers the following chemical
reaction:
2NaN3(s) + 2Na(s) + 3N2(g)

If an automobile airbag has a volume of 11.6 L, what mass of NaN3 (in g) is required to fully inflate the airbag upon impact? Assume STP conditions.

Express your answer in grams to three significant figures.

b

Explanation:

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.
