solution correct answer: consists of a solvent (dissolving medium) and one or more solutes; most of its properites are dependent on the properties of the solute Colligative properties correct answer: properties of a solution that depend only on the number of particles dissolved in it, not the properties of the particles themselves. The main ones are boiling point elevation and freezing point depression. Boiling point correct answer: temeperature where vapor pressure equals atoms on the ...

A hydrogen bond is characterized by correct answer: the highly concentrated partial charge between an H atom and F, O, or N atoms Which of the following exhibits hydrogen bonding?CH3OH,HCl,CH2O, HCN correct answer: CH3OH An adhesive force correct answer: is the result of the intermolecular forces that attract different molecules together An Intermolecular Force correct answer: is the result of the intermolecular forces that attract identical molecules Liquids with high surface te...
