Air bags contain a mixture of NaN3, KN03, and SiO2. When ignited, the following reactions take place:

(1) 2NaN3 —> 2Na + 3 N2

(2) ION a + 2KNO3 → K2O + 5Na2O + N2

(3) K2O + Na2Q + SiO2 → alkaline silicate glass

Reactions (2) and (3) are necessary to handle the toxic sodium reaction product from detonation. Set up a stoichiometric table solely in terms of NaN3 (A), KNO3 (B), etc., and the number of moles initially. If 150 g of sodium azide are present in each air bag, how many grams of KNO3 and SiO2 must be added to make the reaction products safe in the form of alkaline silicate glass after the bag has inflated. The sodium azide is in itself toxic. How would you propose to handle all the undetonated air bags in cars piling up in the nation's junkyards.
