Nitric oxide, NO, is formed in the air by lightning during thunderstorms. It has been estimated that 36 trillion grams of nitrogen are fixed annually as a result of this electrical phenomenon. The equation is: N2(g) O2(g) 2 NO(g) Suppose 70.0 g of air, which contains 53.6 g of nitrogen and 16.5 g of oxygen, is converted to nitric oxide until one of the gases is used up. Of the two gases, what would be left
