Dillon shakes a bottle of oil and vinegar salad dressing. The dressing mixes temporarily, but does not stay mixed. What property of the ingredients makes them separate?

Oil and vinegar have different chemical properties, so they do not dissolve into a stable mixture. Shaking disperses the oil into droplets temporarily, but the liquids separate again when left alone. The correct choice is “The oil and vinegar have different chemical properties.”
