In the manufacture of nitric acid, ammonia can be oxidized to nitrogen monoxide and water. The formula for that equation is 4NH₃(g) + 5O₂(g) → 4NO(g) + 6H₂O(l). Two questions:
a) If 3500 L of ammonia is used, how many L of oxygen are needed to completely react with the ammonia?
b) How many liters of nitrogen monoxide are produced?
