The overall energy involved in the formation of cscl from cs(s) and cl2(g) is −443 kj/mol. given the following information: heat of sublimation for cs is +76 kj/mol, bond dissociation energy for 12cl2 is +121 kj/mol, ei1 for cs is +376 kj/mol, and eea for cl(g) is −349 kj/mol. what is the magnitude of the lattice energy for cscl? express your answer numerically in kilojoules per mole.

In the cathode ray tube experiment, j. j. thomson passed an electric current through different gases inside a cathode ray tube in the presence of an electric field. in which two ways did this experiment change scientists’ understanding of the atom?

In the space, show a correct numerical setup for calculating the number of moles of co2 present in 11 grams of co2

Pegmatites are igneous rocks in which the individual minerals are very large. typically, the minerals are all light-colored quartz, feldspar and muscovite. if you were given a black and white photograph of a pegmatite in a quarry (where the rock has been blasted and broken), what physical properties could you use to identify those three minerals in this hypothetical photo? describe each mineral and the specific diagnostic properties. be specific.
