A solution of water and a nonvolatile,nonionizing compound is placed in a tube with a semipermeable membrane on one side.The tube is placed in a beaker of pure water.What initial net effect will occur?
A)Water will flow from the beaker to the tube.
B)Water will flow from the tube to the beaker.
C)The compound will pass through the membrane into the solution.
D)Nothing will move through the membrane either way.
E)Equilibrium is immediately established.

The solution in the tube contains a nonvolatile, nonionizing compound, which means that it will not affect the concentration of water molecules in the solution. However, the solution in the tube will have a lower water concentration compared to the pure water in the beaker. Therefore, water molecules will diffuse from the higher concentration in the beaker to the lower concentration in the tube across the semipermeable membrane until equilibrium is reached. This means that water will net flow from the beaker to the tube.
