Solution: Nitrogen and hydrogen gas react to form ammonia according to the reaction:N2(g) + 3H2(g) → 2NH3(g)If a flask contains a mixture of reactants represented by the image at the far left, which image below best represents the mixture in the flask after the reactants have reacted as completely as possible?

Problem
Nitrogen and hydrogen gas react to form ammonia according to the reaction:

N2(g) + 3H2(g) → 2NH3(g)

A flask containing two N2 molecules, each depicted as two blue spheres combined, and eight H2 molecules, each depicted as two smaller white spheres combined.

If a flask contains a mixture of reactants represented by the image at the far left, which image below best represents the mixture in the flask after the reactants have reacted as completely as possible?

Three flasks: a, b, and c. Flask a contains two NH3 molecules, each depicted as a blue sphere combined with three smaller white spheres, and also contains one N2 molecule, depicted as two blue spheres combined, and five H2 molecules, each depicted as two smaller white spheres combined. Flask b contains four NH3 molecules, each depicted as a blue sphere combined with three smaller white spheres. Flask c contains four  NH3 molecules, each depicted as a blue sphere combined with three smaller white spheres as well as two H2 molecules, each depicted as two smaller white spheres combined.
