N2 + 3H2 → 2NH3 in this equation How many moles of NH3 can be made if 7.5 moles of H2 react with enough N2
Lena [83]

Answer:

5 moles of ammonia would be formed.

Explanation:

Given data:

Moles of NH₃ formed = ?

Moles of H₂ react = 7.5 mol

Solution:

Chemical equation:

N₂ + 3H₂       →    2NH₃

Now we will compare the moles of ammonia with hydrogen.

             H₂              :           NH₃

              3               :             2

             7.5             :          2/3×7.5 = 5

5 moles of ammonia would be formed from 7.5 moles of hydrogen.
