how much sodium azide is in an airbag
A typical airbag contains 50.0 g of sodium azide, NaN3. Upon impact, the airbag deploys and inflates within 40 milliseconds to a volume of about 60 L, at a velocity between 150 and 250 mph.The airbag inflates due to the decomposition reaction of NaN3 and fills with nitrogen gas in the following reaction:odium azide (NaN3) can decompose at 300oC to produce sodium metal (Na) and nitrogen gas (N2). The signal from the deceleration sensor ignites the gas-generator mixture by an electrical impulse, creating the high-temperature condition necessary for NaN3 to decompose.
