As part of an investigation, students combined substances in a beaker to observe chemical reactions. They measured the mass of each substance before and after the reaction. The mass of the reactants was 50.0 grams and the mass of the products was 48.2 grams. Assuming the students did not make any careless errors, what likely explains the change in mass?

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.
