Question

Ammonia (NH_3) is a key component in fertilizers and household cleaners. Ammonia is produced when hydrogen (H_2) reacts with nitrogen (N2) as seen in the reaction below.

H_2 + N_2 → NH_3

a. Balance the chemical equation for the production of ammonia.
b. What is the mole ratio of H_2 to N_2?
c. How many moles of ammonia are produced from 9 moles of H_2?

Answer 1

The balanced equation for the production of ammonia is N2(g) + 3H2(g) → 2NH3(g), resulting in a mole ratio of 3:1 for H2 to N2. From 9 moles of H2, 6 moles of NH3 are produced.

Step-by-step explanation:

Ammonia is an important chemical used in fertilizers and household cleaners. It is produced through the Haber process, which involves the reaction of hydrogen gas (H2) with nitrogen gas (N2).

The balanced chemical equation for the production of ammonia (NH3) from nitrogen (N2) and hydrogen (H2) is:

N2(g) + 3H2(g) → 2NH3(g)

The mole ratio of hydrogen to nitrogen in the balanced equation for ammonia production is 3:1. This means for each mole of nitrogen; three moles of hydrogen are required.

Using the balanced equation, for every 3 moles of H2, 2 moles of NH3 are produced. Thus, from 9 moles of H2, the amount of ammonia produced would be:

(9 moles H2 / 3 moles H2 per 2 moles NH3) × 2 moles NH3 = 6 moles NH3
