Shown here are molecular views of two different possible mechanisms by which an automobile airbag might function. One of these mechanisms involves a chemical reaction and the other does not. By looking at the molecular views, can you tell which mechanism operates via a chemical reaction?
When an airbag is detonated, the bag inflates. These figures show two possible ways in which the inflation may happen.
Here, we are going to identify which of the mechanisms given operates via a chemical reaction.
Air bags are actually inflated by the following chemical reaction:
2NaN3 → 2Na + 3N2↑
The nitrogen gas produced in the reaction inflates...
