  1. Gas Stoichiometry Using the Ideal Gas Law In Chemical Reactions.

  2. The Automotive Airbag The airbag is responsible for saving many thousands of lives and represents an important application of Gas Stoichiometry.

  3. The Automotive Airbag

  4. The Automotive Airbag The idea of providing protection for occupants of vehicles using some type of cushioning device is not new.

  5. The Automotive Airbag Today’s modern airbag systems inflate in milliseconds and have proven so effective that they are now required on all cars sold in the USA and most other countries.

  6. Most airbag systems use technology first developed by Mercedes Benz which uses a chemical reaction to produce a gas that inflates the bag.
