How many moles of H2O can be formed when 4.5 moles of NH3 react with 3.2 moles of O2?

1 answer:

3 0

Hi Sentpain! Thanks for asking a question here on Brainly.

Solving:

4 NH3 +5 O2 = 4 NO + 6 H2O

☛ Find the ratio for NH3 and O2. That's 4:3
☛ 4.5 x 5 /4 = 5.6
☛ Find the ratio for O2 and H2O. That's 5:6
☛ 3.2 x 6 / 5 = 3.8

Answer: 3.8 mol H2O - choice A
