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.

Which statement correctly compares the body’s energy storage molecules? Glycogen is the body’s main source of energy, but lipids
Artemon [7]

The correct answer is Glycogen is the body’s main source of energy, but lipids contain most of the body’s stored energy.

The glycogen  is a polymer of the glucose. The carbohydrates are the main source of the energy in our body. The glucose that is left after the normal energy utilisation by the body is converted into the glycogen and stored at various location, but the most of the energy reserves of our body lies in the fats, which is stored in form of lipids.
