A sample of neon occupies 3.25 L at 35ºC and 1829 mm Hg. What will the temperature of the gas be, in degrees Celsius, at a volume of 4250 mL and a pressure of 1.25 atm?

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.
