Take a look at the picture. 

Do you see how there are more C molecules on the A (left) side? 

Well, over time, diffusion will happen. 

What that means is that some of the C molecules will move, 
from the A side, over to the B side, 
until both the A and B sides are balanced. 

DIFFUSION is all about BALANCE. 

Since there are more C molecules on the A side, 
some of them will eventually move over to the B side, 
until both A and B sides have the same number of C molecules.
