Consider an ionic compound, mxmx , composed of generic metal mm and generic, gaseous halogen xx . the enthalpy of formation of mxmx is δh∘f=−421δhf∘=−421 kj/mol. the enthalpy of sublimation of mm is δhsub=155δhsub=155 kj/mol. the ionization energy of mm is ie=401ie=401 kj/mol. the electron affinity of xx is δhea=−321δhea=−321 kj/mol. (refer to the hint). the bond energy of x2x2 is be=239be=239 kj/mol. determine the lattice energy of mxmx .

How do the measurements of charge at the different locations on the sphere compare to each other? the charge measurements are different at all locations on the sphere. the charge measurements are virtually not the same at all locations on the sphere except for the charge at the very top and at the very bottom that are equal. the charge measurements are virtually the same at all locations on the sphere except for the charge at the very top. at the top, the conductive sphere has a small disk that is made of different material. the charge measurements are the same at all locations on the sphere. what happens to the charge on the conductive sphere when it is connected to a source of charge such as the electrostatic voltage source? nothing will happen because no charge goes around the surface of the sphere. the charge on the conductive sphere spreads out over the surface of the sphere; being greater in some specific locations on the sphere. the charge on the conductive sphere spreads out uniformly over the surface of the sphere. the charge on the conductive sphere spreads out non-uniformly over the surface of the sphere.

Avertical clean glass piezometer tube has an inside diameter of d = 1 mm and is used to measure pressure in a horizontal pipe carrying water as shown. due to pressure in the pipe, the water at 20c rises into the tube to a height h. if the water pressure in the pipe is p = 500 pa gauge, estimate the height h: (a) without considering surface tension (b) with surface tension (capillary) effects. the contact angle  can be assumed at 30 deg
