Chemistry is everywhere. Even where you don't expect it. With the 'chemistry =' poster campaign we want to show how self-explanatory chemistry actually is. Want to know more about the chemistry involved? Scroll down for additional information.
A car’s airbag is connected to sensors via a computer. Together, these are able to detect the collision. Ignition of the propellant causes a superfast chemical reaction that fills the airbag with nitrogen gas.
Violent reaction
The main constituent of the airbag explosive is a reactive alkali-metal. The nitrogen is chemically bound in this. Ignition of the propellant causes a violent reaction with an oxidizer, during which lots of nitrogen is generated. Within a tenth of a second from the first impact – quicker than the wink of an eye – the cushion is ready to receive your head.
