Conduct Internet research to learn how airbags work in automobiles. Take notes on your research. Then write one to two paragraphs explaining what causes airbags to inflate when a car is involved in an accident. Sodium azide (NaN3) is a substance that can be used to inflate airbags. An electrical impulse causes the sodium azide to decompose, producing elemental sodium and nitrogen gas. Write the balanced chemical equation for this reaction.
