Answer:
The balanced equation is: 4NH₃(g) + 5O₂(g) → 4NO(g) + 6H₂O(I)
4 moles of ammonia need 5 moles of oxygen to react, in order to produce 6 moles of water and 4 moles of nitrogen oxide.
Explanation:
NH₃(g) + O₂(g) → NO(g) + H₂O(I)
That is the unbalanced equation.
Ratio is 1:1, so 1 mol of ammonia and 1 mol of oxygen may react to produce 1 mol of NO and 1 mol of water
First of all we need to balance. Let's count the atoms:
In reagent side, we have 3 H and in product side there are 2H, we can add a 3, so now we have 6 H. Therefore, the reagent side must have 2 in front of the ammonia. In both sides we have 6 H
Now, that we added a 2 in the ammonia, we have 2N, so we have to add 2 to NO in the product side.
Let's count the oxygen in the product side, 5. We must add 5/2 in the reactant side. But chemical equations usually do not have rational numbers, that's why we multiply x2, all the stoichiometry.
The balanced equation is: 4NH₃(g) + 5O₂(g) → 4NO(g) + 6H₂O(I)
4 moles of ammonia need 5 moles of oxygen to react, in order to produce 6 moles of water and 4 moles of nitrogen oxide.
