Question

Airbags protect occupants by inflating when a car crashes,
Airbags rely on chemical reactions to produce large volumes of gases quickly,
In some airbags, solid sodium azide (NaNg) decomposes forming nitrogen gas and sodium
as the only products,
M
A passenger airbag requires 120 dm of gas to fill
it
Calculate, using the ideal gas equation the mass of sodium azide required to fill a
passenger airbag in this reaction under standard conditions (101 kPa. 25°C).
Give your answer to an appropriate numb of significant figures.

Answer 1

Answer:

The chemical at the heart of the air bag reaction is called sodium azide, or NaN3. CRASHES trip sensors in cars that send an electric signal to an ignitor. The heat generated causes sodium azide to decompose into sodium metal and nitrogen gas, which inflates the car's air bags.
