What happens when two solutions separated by a selectively permeable membrane reach osmotic equilibrium?

See explanation.

Explanation:

When two solutions with different concentrations are separated by a selectively permeable membrane, the solvent flows from the lowest concentration to the higher concentration.

After reach osmotic equilibrium, both of the solutions will have the same amount of solvent, it means they will have the same concentrations.

i'm assuming that the correct answer is indeed the first one/ "a"..

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
