A student performs an experiment to determine the melting point of ice in order to investigate the strength of electrostatic forces between its molecules. Once the student completes the experiment, which additional action should the student take?

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.
