Match the following properties of liquids to what they indicate about the relative strength of the intermolecular forces in that liquid. Strong intermolecular forces: Weak intermolecular forces: -high boiling point -high vapor pressure -high surface tension -high viscosity
1.Surface tension is due unbalanced intermolecular forces between molecules at A. A surface of a single liquid B. A surface between two immiscible liquids C. A surface between two miscible liquids D. Mixture of gases
1.Pentane (C5H12) has a surface tension of 1.61 x 10 ^ -2, while ethanol (C2H5OH) has a surface tension of 2.23 x 10 ^ -2, which would have the highest viscosity? A) pentane B) ethanol C) both have the same viscosity D) cannot be determined with the information provided 2.Which of the following is true for surface tension? l is a measure of the surface area exposed by the liquid ll increases with increasing intermolecular attraction forces lll decreases with...
i neds help with all the question 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....
*Explanations should be brief. Draw a box around each final answer, if applicable.* 1. Consider intermolecular forces and kinetic energies with respect to a solid and a liquid. Explain why molecules in a liquid are free to move past each other, while molecules in a solid are held in fixed positions. 2. Use your knowledge of intermolecular forces to provide an explanation for why the boiling point of 2-hexanol is higher than the boiling point of 2,3-dimethyl-2-butanol. Be sure to...

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...
