QUESTION 10
Information - Colligative
Properties
Colligative properties of solutions are those properties which
depend only on the number of dissolved solute particles in solution
not the chemical properties of the solute. For example when a
solute is dissolved in a solvent, vapor pressure

Which of the following best describes London dispersion forces. Question 1 options: the intermolecular forces that exist when ions from an ionic compound are attracted to the dipole of polar molecules in a mixture. involves molecular orientations in which the positive end of one dipole is near the negative end of another forces that exist only between molecules that contain hydrogen atoms bonded to highly electronegative atoms such as O, N, F. Interactions between temporary dipoles cause atoms to be...
