If three molecules of hydrogen react with one molecule of nitrogen how many molecules of ammonia would be formed?

Answer : The number of molecules of ammonia formed would be, 2.

Explanation :

As per question, when the hydrogen molecule react with nitrogen molecule then it gives ammonia as a product.

The balanced chemical reaction will be :

By the stoichiometry we can say that, 1 mole of nitrogen gas react with 3 mole of hydrogen gas to give 2 mole of ammonia gas as product.

The number of molecules of nitrogen gas = 1

The number of molecules of hydrogen gas = 3

The number of molecules of ammonia gas = 2

Therefore, the number of molecules of ammonia formed would be, 2.

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
