Question

How many molecules of ammonia are formed in the following equation: N2+3H2→2NH3

Answer 1

Answer:

• two molecules of ammonia are formed by the reaction of one nitrogen and three hydrogen molecules.

Explanation:

The  balanced chemical equation provides information on:

• Reactants: those are the compounds that appear of the left side of the equation, each with its chemical formula.

• Products: those are the compounds that appear on the right side of the equation, again, each with its chemical formula.

• Ratio: the coefficients of each compound (the number to the left of the chemical formula) represent the ratio of the number of molecules that react and are formed.

In the given equation you have:

• Equation: N₂ + 3H₂ → 2NH₃

• The coefficients are 1 for nitrogen, 3 for hydrogen, and 2 for ammonia. Hence, 2 molecules of ammonia are formed by the reaction of 1 molecule of nitrogen and 3 molecules of hydrogen.
