Question

4 NH3 + 5 O2→ 4 NO + 6 H2O

If 4.00 mol of water are formed, how many moles of NO will be formed?

Answer 1

Answer:

4NH

3

+5O

2

⟶4NO+6H

2

O

1NH

3

+1.25O

2

⟶1NO+1.5H

2

O

Hence 1 mole of NH

3

reacts with .125 moles of O

2

to produce 1 mole of NO and 1.5 moles of H

2

O. Hence when one mole of ammonia and one mole of oxygen are made to react to completion, then all the oxygen are made to react to completion, then all the oxygen is consumed
