Ammonia (NH3) and oxygen combine to form nitrogen monoxide (NO) and water by the chemical reaction:
4 NH3(g) + 5 O2(g) → 4 NO(g) + 6 H2O(l)
If 100 grams of ammonia are reacted with 100 grams of oxygen
a. Which reagent is the limiting reagent?
b. How many grams of the excess reagent remains at completion?
