11. Which of the following statements regarding solubility is INCORRECTIT a. A nonpolar solvent will not interact strongly enough with a nonpolar substance to form a solution. The b. Nonpolar liquids are miscible because the intermolecular forces in the pure liquids are weak, and there is an increase in the probability of the mixed state. c. The solubility of a gas in water typically increases with increasing temperature. d. A polar solvent will dissolve an ionic compound due to ion-dipole interactions. e. The solubility of most solids increases with increasing temperature. Twe 12. Which of the following concentration measures will change in value as the temperature of a solution changes? a. Mole fraction b. Molarity c. All of these are correct d. Molality e. Mass percent 13. Which of the following statements is INCORRECT? a. Evaporation is an endothermic process, since heat is absorbed when a substance vaporizes. b. The phase change from solid to gas is exothermic. c. A liquid which has a high boiling point has a lower vapor pressure at a given temperature than a liquid with a low boiling point. d. Since rubbing alcohol evaporates more readily than water, one would assume that the alcohol has weaker intermolecular forces. e. Liquids boil at higher temperatures in the mountains due to the higher altitude
