44) KBr does not dissolve well in nonpolar solvents because A) solute-solute interactions are much larger than solvent-solvent or solute-solvent interactions. B) solvent-solvent interactions are much larger than solute-solvent or solute-solute interactions. C) solute-solvent interactions are much larger than solvent-solvent or solute-solute interactions. D) solute-solvent interactions are similar to solvent-solvent and solute-solute interactions. 45) Commercial cold packs often contain solid NH4NO3 and a pouch of water. The temperature of the pack drops as the NH4NO3 dissolves in water. Therefore, for the dissolving of NH4NO3 in water, A) AHsoln is negative and ASsoln may be negative or positive. B) AHsoln is negative and ASsoln is positive. C) AHsoln is positive and ASsoln may be negative or positive. D) AHsoln is positive and ASsoln is positive. 46) What are the major solute-solvent interactions created when HOCH2CHOH dissolves in water? A) dipole-dipole B) dispersion C) hydrogen bonding D) ion-dipole
