Chemical Analysis A scientist wants to identify an unknown compound on the basis of its physical
properties. The substance is a white solid at room
temperature.
Allempts to determine its boiling point
were unsuccessful. Using Table 6. name the unknown
compound.

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.
