In the process for the manufacture of chlorine by direct oxidation of hcl with air over a catalyst to form cl2 and h2o (only), the exit product is composed of mole fractions of cl2 (21.4%), h2o (21.4%), and n2 (45.0%) – the remainder is hcl and o2. calculate and /or identify: (a) the limiting reactant? (b) the percentage excess reactant? (c) the degree of completion of the reaction? (d) the extent of reaction?

Which of the following is a compound? a.carbon b.oxygen c.hydrogen d.water

Which of the following statements about hybrid orbitals is or are true? choose all that apply. choose all that apply. under sp2 hybridization, the large lobes point to the vertices of an equilateral triangle. after an atom undergoes sp hybridization there is one unhybridized p orbital on the atom. the angle between the large lobes of sp3 hybrids is 109.5∘

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.
