Chapter 10, Problem 10E

Neon and HF have approximately the same molecular masses.

(a) Explain why the boiling points of Neon and HF differ.

(b) Compare the change in the boiling points of Ne, Ar, Kr, and Xe with the change of the boiling points of HF, HCl, HBr, and HI, and explain the difference between the changes with increasing atomic or molecular mass.

Examining the crystal structure of CsCl (Caesium Chloride), the Cs+ions form the 8 corners of a cube and the Cl−ion is a the center of the cube. From first-principles calculation, it was determined that the lattice constant of CsCl is 4.209 ̊A. (a) Calculate in detail the electrostatic force exerted by all the Cs+ atoms to the Cl−atom; (b) Assuming that 1 Cs+atom is missing in crystal structure (crystal is said to have a defect), calculate in detail what will be the net electrostatic force on the Cl−ion due to the remaining Cs+ions.
