# Problem: Nitrogen (N2) and hydrogen (H2) react to form ammonia (NH3). Consider the mixture of N2 and H2 shown in the accompanying diagram. The blue spheres represent N, and the white ones represent H.How many N2 molecules are left over?

###### FREE Expert Solution

Reaction:    N2 + H2 → NH3

Balanced Reaction:   N2 + 3 H2 → 2 NH3 Blue spheres represent N (2 blue spheres together = N2):

4 molecules N2

White ones represent H (2 white spheres together = H2):

9 molecules N2

Calculate how much NH3 can be produced by each reactant:

From 4 molecules N2

NH3 molecules = 8 molecules

From 9 molecules H2
