For the reaction 2SO2 (g) + O2<—> 2SO3(g), The equilibrium concentrations of the sulfur oxides are [SO2] =2.00M and the [SO3]=10.0M what is the equilibrium concentration of oxygen when the KEQ is 800.0 for the reaction

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.
