Homework Answers
Option A is the correct one. At the liquid surface-air interface, the inward pull experienced by the surface molecules gives rise to surface tension.

Question 4 Which of the following is or are false? Surface tension of liquids increases as temperature increases. Liquids are normally about 90-95% as dense as their corresponding solid Liquids are about 1000 times denser than gases Molecules with high intermolecular forces will have high surface tension The viscosity of a liquid is a measure of its resistance to flow.

1. Indicate which is the strongest intermolecular force between each of the two molecules below: a. H2S and H2O b. C4H10 (butane) and (CH3)2CO (acetone) 2. Considering properties of liquids: a. Surface tension is proportional to the magnitude of intermolecular forces and/or attractive forces among the molecules in the liquid. With this perspective in mind, which in the following pair of liquids would have the highest surface tension: H2O or CHCl3 (chloroform) b....

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...
