The chemical equation for the formation of ammonia is unbalanced. 3H2 (g) + N2 (g) NH3 (g) If three molecules of hydrogen react with one molecule of nitrogen, how many molecules of ammonia would be formed?

The answer to your question is 2 molecules of ammonia

Explanation:

Reaction

3H₂ (g) + N₂ (g) ⇒ NH₃ (g)

Balance the reaction

Reactants Products

Hydrogen six three

Nitrogen two one

Then, to balance this reaction, multiply the products by 2.

3H₂ (g) + N₂ (g) ⇒ 2 NH₃ (g)

Reactants Products

Hydrogen six six

Nitrogen two two

Now, the reaction is balanced, and 2 molecules of ammonia will be formed.
