Predicting #1- I think that talcum powder or cornstarch is a material least important for the proper inflation of the air bag. It will be necessary to have a precise stoichiometry ratio to know the exact quantity of sodium azide that will inflate the air bag with nitrogen gas.
r bags are located inside automobiles. The air bag is in front of the passenger seat inside the dashboard. Once the vehicle gets into a crash the air bag pops out. The air bags are filled nitrogen gas. Hazardous sodium metal is also produced with the nitrogen so the potassium nitrate adapts with the sodium to make the hazardous sodium oxide less harmless. The uses of the stoichiometry calculations are to figure out the amount of sodium azide that produces the required nitrogen gas to fill the air bag. If there is too much gas that is
