The sodium azide required for automobile air bags is made by the reaction of sodium metal with dinitrogen monoxide in liquid ammonia:

(a) You have 65.0 g of sodium, a 35.0-L flask containing N₂O gas with a pressure of 2.12 atm at 23°C, and excess ammonia. What is the theoretical yield (in grams) of NaN₃?
(b) Draw a Lewis structure for the azide ion. Include all possible resonance structures. Which resonance structure is most likely?
(c) What is the shape of the azide ion?
