4 NH3 + 6 NO = 5 N2 + 6 H2O

Question

I don't understand moles and don't know how to ratio this equation. The equation is already balanced.

1. 10 moles of NO react with __________ moles of NH3-
2. 5 moles of NO produce __________ moles of N2-
3. The production of 6 moles of N2 requires __________ moles of NO
4. 10 moles of NO produce __________ moles of H2O
5. __________ grams of H2O are formed fro 3 moles of NH3-

Answer 1

Look at the balanced equation. The coefficients in front of each tells you the stoichiometry, i.e. the mole ratios. You can then use dimensional analysis as follows:

10 NO X 4 NH₃/6 NO = 6.7 moles NH₃

5 NO X 5 N₂/6NO = 4.2 moles N₂

6 N₂ x 6 NO/5 N₂ = 7.2 moles NO

ETC, ETC. See if you can do the others.
