Carbon tetrafluoride, CF4 contains four identical C-F bonds. Fluorine is more electronegative than carbon. How will this impact each of the bonds between carbon and fluorine

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.
