Final answer:
The total number of moles of NO produced when 1.0 mole of O2 is completely consumed is 0.8 moles.
Step-by-step explanation:
To determine the total number of moles of NO produced when 1.0 mole of O2 is completely consumed, we need to use the mole ratio from the balanced equation. From the given reaction: 4NH3 + 5O2 → 4NO + 6H2O, we can see that the mole ratio between O2 and NO is 5:4. This means that for every 5 moles of O2 consumed, 4 moles of NO are produced. Therefore, if 1.0 mole of O2 is consumed, we can calculate the number of moles of NO produced:
1.0 mole O2 * (4 moles NO / 5 moles O2) = 0.8 moles NO
So, the total number of moles of NO produced when 1.0 mole of O2 is completely consumed is 0.8 moles.
