Answer:
1:4.
Explanation:
- According to the balanced equation,
3Cu + 8HNO₃ → 3Cu(NO₃)₂ + 2NO + 4H₂O,
- It is clear that every 3.0 moles of Cu reacts with 8.0 moles of HNO₃ to produce 3.0 moles of Cu(NO₃)₂, 2.0 moles of NO and 4.0 moles of H₂O.
∴ The ratio of NO produced to HNO₃ reacted is 2:8 which is 1:4.
