Question

question 2
experiment 7.1: which dye should have traveled faster through the gel?
potassium permanganate
methylene blue
question 3
the solution in beaker 1 is select compared to the bag solution. this is because the concentration in the beaker is select the concentration in the bag. as a result, the bags weight select because water moved select of the bag.
question 4
the solution in beaker 2 is select compared to the bag solution. this is because the concentration in the beaker is select the concentration in the bag. as a result, the bags weight select because water moved select of the bag.

Explanation:

For Question 2, Potassium Permanganate has a smaller molecular size compared to Methylene Blue. Smaller - sized molecules generally diffuse faster through a gel matrix. For Questions 3 and 4, without specific concentration values, we rely on the principles of osmosis. If the beaker solution has a lower solute concentration (hypotonic) compared to the bag, water will move into the bag and increase its weight. If it has a higher solute concentration (hypertonic), water will move out of the bag and decrease its weight. If the concentrations are equal (isotonic), there will be no net movement of water and the bag's weight will remain the same.

Answer:

Question 2: Potassium Permanganate
Question 3: Without specific concentration data, cannot be fully answered. But possible scenarios: If the beaker solution is hypotonic compared to the bag solution (because the concentration in the beaker is lower than the concentration in the bag), as a result, the bag's weight increases because water moved into the bag. If hypertonic, the bag's weight decreases as water moves out. If isotonic, the weight remains the same.
Question 4: Similar to Question 3, without specific concentration data, cannot be fully answered. But scenarios follow the same osmosis - based principles as in Question 3.
