Question:
One well known characteristic of gases in that the expand to fill their containers and assume the shape of their containers.  A practical application of these characteristics is the reaction that forms N2 (g) in an automobile air-bag safety system. This reaction utilizes the rapid decomposition of sodium azide.

2NaN3(s) à Na(l) + 3N2(g)

The essential components of the system are an ignition device and a pellet containing sodium azide.  When activated, the system inflates and air bag in a very short time (milliseconds range).  Note: the liquid sodium is converted to harmless solid sodium due to special additives that are also present initially.




Which statement regarding the above chemical reaction is true:
