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...

QUESTION 15 Which statement A-D about the first law of thermodynamics (AEsystem-q+w) is not correct? O q is the energy added to or removed from the system by a temperature difference. O w is the energy added to or removed from the system by a deformation: that is, a force moves something. AEo stem is the change in the Gibbs free energy of the system. O If the only work that is done is P-V work, then q -the change...
