5. (9pts) Ammоniа (NH3) cаn reаct with оxygen (O2) tо form nitrogen (N2) and water (H2O). Write the complete balanced reaction equation. (for your convenience, the unbalanced reaction equation is given below.) __NH3 + __O2 ⟶ __N2 + __H2O Below is a “before reaction” picture showing the amount of ammonia and oxygen present for a reaction. Assume these molecules are all the reactants that are present before the reaction proceeds. Draw an “after reaction” picture showing all the product molecules formed and any leftover reactant molecule(s) (if any is present). Assume the reaction goes to completion (produces the maximum amount of product).
