Question

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?

Answer 1

Your answer is 2

Step-by-step explanation:

I took the test and got it correct

Answer 2

Answer: 2 molecules of ammonia

Step-by-step explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

The balanced chemical equation for the formation of ammonia is:

`3H_2(g)+N_2(g)\rightarrow 2NH_3`

According to stoichiometry,

3 molecules of hydrogen combines with 1 molecule of nitrogen to give 2 molecules of ammonia.
