Air bag and sodium azide
Hi,
I am having problems with this one....
Air bags are activated when a severe impact causes a steel ball to compress a spring and electrically ignite a detonator cap. This causes sodium azide (NaN3) to decompose explosively according to the following reaction...
2NaN3 -----> 2Na + 3N2
What mass of NaN3 must be reacted to inflate an air bag to 70.0 L @ STP?
Any ideas??
Thanks.
