Given the balanced equation, 4 NH3 + 3 O2 Imported Asset 2 N2 + 6 H2O, what is the molar ratio of NH3 to N2?

Answer is 2 : 1.

Explanation;

Reaction between NH₃ and O₂ can give N₂ and H₂O as products. The balanced reaction equation is

4NH₃ + 3O₂ → 2N₂ + 6H₂O

According to the balanced equation, 4 molecules of NH₃ react with 2 molecules of N₂.

Hence, the stoichiometric ratio between NH₃ and N₂ is 2 : 1.

Stoichiometric ratio = molar ratio

Hence, molar ratio between NH₃ and N₂ is 2 : 1. This can be written as

moles of NH₃ / moles of N₂ = 2 / 1
