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.
2 NaN3(s)--> 2 Na(s) + 3 N2(g)
What mass of NaN3(s) must be reacted in order to inflate an air bag to 67.5 L at STP?
never mind, I figured it out.
