Chemicals involved in airbag deployment:
NaN3
Na
K2O
SiO2
KNO3
N
Reactions:
1. NaN3 --> Na + N2
2. Na + KNO3 --> K2O + Na2O + N2
3. K2O + Na2O + SiO2 --> alkaline silicate
Reactants: 2NaN3; 10Na; 2KNO3; K2O; Na2O; SiO2
Products: 2Na; 3N; K2O; 5Na2O; N2
Initial Reactant: 2NaN3 Final Product:
Other chemicals used: Helium; Argon
Balanced Reactions:
1. 2NaN3 --> 2Na + 3N2
2. 10Na + 2KNO3 --> K2O + 5Na2O + N2
3. K2O + Na2O + SiO2 --> alkaline silicate
Using the ideal gas equation, 0.3 g of N2 gas are generated when the airbag deploys.
NaN3, KNO3, and SiO2 are in the airbag molecule.
0.6 moles of NaN3 are needed in order to inflate an airbag.
1.2 grams of Na are produced in the first reaction
2 grams of KNO3 are needed to completely react with Na
