Homework Help: Chemistry

Posted by Anonymous on Friday, April 10, 2009 at 9:43pm.

I got some questions about air bags. Can someone please help me out? Thamks in advance for giving me any information about that.

1. Which starting material used in the air bag inflator is least important for the proper inflation of the air bag? Would it be necessary to have it present in a precise stoichiometric ratio? Why or why not?

2. What is the correct stoichiometric ratio between NaN3 and KNO3 to ensure no sodium is unreacted? What would be the consequences of an excess of KNO3 to the operation of an air bag?

I knew the balanced equations that undergo these reactions...
2NaN3-->2Na+3N2
10Na+2KNO3-->K2O+5Na2O+N2
K2O+ Na2O+SiO2-->glass
I hope this can help...
