4NH3 + 5O2 → 4NO + 6H2O
2NO + O2 → 2NO2
3NO2 + H2O → 2HNO3 + NO

In this process, the NO made in the last reaction is recycled back into the second reaction and used as a reactant. In the end, all of the NO produced is recycled back so that when the manufacturing process is complete, essentially no NO remains. If a chemist starts with 50.0 grams of NH3 and an excess of water and oxygen, what mass of nitric acid can be made

    Consider the following equation, which represents the combustion of ammonia.

    4NH3(g) + 3O2(g) --> 2N2(g) + 6H2O(g)

    How many moles of O2(g) is required to form 10 mol of H2O(g) is burned?
