Question

osmosis across a cell membrane can be modeled using a u - shaped tube. this diagram of a u - shaped tube shows two solutions immediately after they were poured into the tube. the solutions were made by dissolving different amounts of the same solute in water. according to the diagram, which statements describe the solutions immediately after they were poured into the u - shaped tube? select all that apply. the two solutions are at equilibrium. the two solutions have different concentrations. the two solutions have the same volume. water is the solute in both solutions.

Explanation:

• Equilibrium is not established as solute concentrations differ initially.
• The number of solute particles is different, so concentrations vary.
• The liquid - level in both arms of the U - tube is the same, indicating equal volumes.
• Water is the solvent, not the solute.

Answer:

The two solutions have different concentrations.
The two solutions have the same volume.
