Alkyl Halide Reactions. The functional group of alkyl halides is a carbon-halogen bond, the common halogens being fluorine, chlorine, bromine and iodine. With the exception of iodine, these halogens have electronegativities significantly greater than carbon.
Its been said that most car companies make it so where airbags deploy based on the impact. It is said that the airbag will not deploy until the impact generates 7 G's of force. For most vehicles that speed is equivalent to hitting an object at 12 mph or hitting another vehicle at 25 to 30 mph. It is dependent upon the impact of the crash.

Inside the airbag is a gas generator containing a mixture of NaN3, KNO3, and SiO2. When the car undergoes a head-on collision, a series of three chemical reactions inside the gas generator produce gas (N2) to fill the airbag and convert NaN3, which is highly toxic, to harmless glass.Sodium azide (NaN3) can decompose at 300oC to produce sodium metal (Na) and nitrogen gas (N2). 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:
