Metallurgical-grade silicon is purified to electronic grade for use in the semiconductor industry by chemically separating it from its impurities. The Si metal reacts in varying degrees with hydrogen chloride gas at 300°C to form several polychlorinated silanes. Trichlorosilane is liquid at room temperature and is easily separated by fractional distillation from the other gases. If 100 kg of silicon is reacted as shown in Figure shown below:   a.     How much trichlorosilane (Stream E) is produced? b.     How much moles of gas stream leaving as overhead distillate (Stream D)?   Si = 28 g/mol; Cl = 35 g/mol ; H= 1 g/mol
