Question: The chemical reaction for making nitrogen dioxide is given by
2O2 + N2 → 2NO2
Suppose we combine nitrogen and oxygen to make 23 g of NO2.
a. How many moles of NO2 does that correspond to?
b. How many moles of N2 are required?
c. How many molecules of O2 are required? Express your answer in terms of NA.
d. If the reaction produces 10 L of NO2, what are the volumes of O2 and N2? Explain your reasoning
