Nitrogen monoxide and oxygen react to form nitrogen diox- ide. Consider the mixture of NO and O2 shown in the accom- panying diagram. The blue spheres represent N, and the red ones represent O. (a) Draw a representation of the product mixture, assuming that the reaction goes to completion. What is the limiting reactant in this case? (b) How many NO2 mole- cules would you draw as products if the reaction had a percent yield of 75%? [
