1 molecule of nitrogen (N2) reacts with 3 molecules of hydrogen (H2) to produce some amount of ammonia (NH3).

Question

Use the number of atoms in the products to answer the question below.
Chemical element Number of atoms in reactants Number of atoms in products
H 6 6
N 2 2
During this reaction, how many molecules of ammonia (NH3) are produced?

Answer 1

The balanced chemical equation for the reaction between nitrogen (N₂) and hydrogen (H₂) to produce ammonia (NH₃) is:

\[ N_2 + 3H_2 \rightarrow 2NH_3 \]

From this equation, we can see that 1 molecule of nitrogen reacts with 3 molecules of hydrogen to produce 2 molecules of ammonia.

To find the number of molecules of ammonia produced, we can refer to the stoichiometry of the balanced equation. Since 1 molecule of N₂ yields 2 molecules of NH₃, we can conclude that:

• The number of molecules of ammonia (NH₃) produced is 2.

Thus, 2 molecules of ammonia (NH₃) are produced during the reaction.
