The free space in a metal may be found by subtracting the volume of the atoms in a unit cell from the volume of the cell. A value of 8.4 kJ/mol would indicate a release of energy upon vaporization, which is clearly implausible. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. d) 0.469 Ethanol ($\ce{C2H5OH}$, molar mass 46) boils at 351 K, but water ($\ce{H2O}$, molar mass 18) boils at higher temperature, 373 K.

Discussion - However, a distinction is often made between two general types of covalent bonds. Chung (Peter) Chieh (Professor Emeritus, Chemistry @University of Waterloo). All of these factors will affect the lattice energy and therefore the melting points. You can have all kinds of intermolecular forces acting simultaneously. It is often recommended that you let your car engine run idle to warm up before driving, especially on cold winter days. The strength of dispersion forces increases as the total number of electrons in the atoms or nonpolar molecules increases. ii) Viscosity increases as molecular weight increases.

The individual dipoles point from the $\ce{H}$ atoms toward the $\ce{O}$ atom. Step 1: List the known quantities and plan the problem. The atom with the greater electronegativity acquires a partial negative charge, while the atom with the lesser electronegativity acquires a partial positive charge. Asking for help, clarification, or responding to other answers. Both NaF and CsCl are ionic compounds with the same charges on the cations and anions. A dipole-dipole attraction is a force that results from an electrostatic attraction of the positive end of one polar molecule for the negative end of another polar molecule (e.g., [latex]\ce{ICI}[/latex] molecules attract one another by dipole-dipole interaction).
