solute A are strongly solvated by water, whilethose of solute B are only weakly solvated.Which of the two dissolution processes is moreexothermic, on a kJ/mol basis? 1.It depends on the molecular weights ofthe solutes.2.Both processes are equally exothermic.3.dissolving B in water4.dissolving A in watercorrect5.Cannot be answered without knowing theidentities of the solutes.Explanation:Since the solvation process is exothermic,dissolving A (the more strongly solvated so-lute) will be more exothermic process.00910.0 pointsEthyl alcohol (CH3CH2OH) is/is not solublein water.1.is; ethyl alcohol exhibits dipole-dipole andH-bonding interactions with water.correct2.is not; ethyl alcohol exhibits dispersionforces which are insufficient for dissolving.

jung (jj23596) – Homework 2 – Sutcliffe – (52440) 3 3.is; all organic molecules are soluble inwater.4.is not; ethyl alcohol is an ionic compoundwith a hydroxide group and hydroxides areinsoluble.Explanation:The oxygen on ethyl alcohol has two lonepairs and two polar bonds.Thus, it canform dipole-dipole and H-bonding interac-tions with polar water. 01010.0 pointsWater causes many electrolytes to dissociateWhich of the following statements about col-ligative propertiesof aqueoussolutionsisFALSE?1.Osmosis is a colligative property. 011 10.0 points Henry’s Law would allow one to predict 1. the vapor pressure of the solvent above the pure solvent. 2. the extent of dissociation of solute in solution. 012 10.0 points
