to cushion the driver or passenger during the accident. The airbag deflates 0.3 seconds after it is successfully inflated by this chemical reaction. The overall chemical reaction that occurs is when Sodium Azide reacts with Iron (III) Oxide to produce Sodium Oxide and Iron and Nitrogen Gas. This chemical reaction can be represented with the balanced chemical equation of: 6NaN3(s) + Fe2O3(s)  3Na2O(s) + 2Fe(s) + 9N2(g). The purpose of automobile airbags is to protect a driver or passenger when they are involved in an automobile accident. The car s electrical systems and sensors are the beginning of the process on how the airbag inflates. When the sensors have detected that an automobile has been in an accident it triggers the automobile s airbags to rapidly inflate and deflate

in order for the driver or passenger to be securely cushion during the impact. Chemical reactions occur when these sensors trigger the airbag to be inflated, sodium azide is the propellant used as a reactant to produce nitrogen gas, the gas that the airbag is inflated with. Consequently, the whole process of the inflation of automobile airbags is caused by sensors and a chemical reaction producing nitrogen gas to inflate the airbag.
