how many molecules of ammonia can be created when four molecules of nitrogen are combined with four molecules of hydrogen? include a drawing of the molecules in your answer.

The number of molecules of ammonia formed are:

Explanation:

The number of Nitrogen molecules is 4.

The number of Hydrogen molecules is 4.

The balanced chemical equation for formation of ammonia is:

According to the above equation, 3 molecules of require one molecule of .

So, 4 molecules of    will require   molecules of .

Hydrogen, acts as a limiting reagent. This means that the number of ammonia molecules produced depends only on the number of hydrogen molecules.

Therefore, for 4 molecules of Hydrogen, the number of ammonia molecules produced is  .

The diagram of the ammonia molecule can be obtained from this link:

a.

b.

Explanation:

Hello,

In this case, considering that the dissolution reaction of a solid in aqueous solutions involve the dissociation (separation) of both its cation and anion for the required salts we write:

a.

b.

Thus, a two is required for nitrate anions in a. in order to balance it at the reactant and a three is required for sodium cations in b. in order to balance it as well.

Best regards.
