Question

4NH3+5O2-4NO+6H2O
how many moles of NH3 must react to produce 5.0 moles of NO?​

Answer 1

To produce 5.0 moles of NO, 5.0 moles of NH3 are needed.

Step-by-step explanation:

To determine how many moles of NH3 must react to produce 5.0 moles of NO, we need to use the balanced chemical equation:

4NH3(g) + 5O2(g) → 4NO(g) + 6H2O(l)

This equation tells us that for every 4 moles of NH3, we produce 4 moles of NO. Therefore, to produce 5.0 moles of NO, we would need:

(5.0 moles NO) x (4 moles NH3 / 4 moles NO) = 5.0 moles NH3

So, to produce 5.0 moles of NO, we would need 5.0 moles of NH3 to react.

Answer 2

Answer: 5.0 moles

Step-by-step explanation:

From the equation, we see that for every 4 moles of ammonia consumed, 4 moles of nitrogen monoxide are produced (we can reduce this to moles of ammonia consumed = moles of nitrogen monoxide produced).

This means that the answer is 5.0 mol
