g the following statements as they apply to infrared spectroscopy. Decide if each is true or false. For a given pair of atoms, the vibrational frequency expected if they are joined by a single bond should be higher than if they are joined by a double bond. Because molecules in condensed phases (solids and liquid) are not free to rotate, rotational-vibrational transitions are not observed in their infrared spectra. For this reason, even at high resolution, a condensed phase spectrum is characterized by broad bands. Absorption bands in infrared spectroscopy are due to electronic transitions in molecules. Heteronuclear diatomic molecules such as HCl do not absorb infrared radiation. Air contains nitrogen and oxygen - both of which strongly absorb infrared radiation. For this reason, most FTIR instrument are operated under vacuum.

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.

The lattice enthalpy (formation of ionic solid from ions in the gas phase) for agcl(s) is -916 kj/mol and the hydration enthalpy (dissolution of gaseous ions into water) is -850 kj/mol. how much heat (in joules) is involved in forming 1l of saturated agcl solution (1.8 × 10-4 g / 100 ml water) by dissolving agcl(s)? assume solution volume does not change much upon dissolution. the equations are given below. ag+(g) + cl−(g) æ agcl(s)
