A) There are no solute-solute interactions to break up B) There are no solvent-solvent interactions to break up C) The resulting solute-solvent interactions are especially powerful D) The solubility of gases in water is higher in temperature E) Water is a polar solvent Given the solubility graph below determine which statement is correct. A) Both substance X and Y represent gaseous substances. B) Substance Y is more soluble for a given temperature and quantity of solvent than substance X. C) Substance Y is unsaturated at 30 g/100mL water and a temperature of 100 degree C. D) At 0 degree C substance X is more soluble than substance Y. E) An increase in pressure would cause an increase in solubility for both substance X and Y. Which of the following properties are not considered to be colligative properties? A) Vapor-pressure lowering B) Boiling-point elevation C) Freezing-point depression D)
