Problem- Many computer chips are manufactured from silicon, which occurs in nature as silicon dioxide. When silicon dioxide is heated to melting, it reacts with solid carbon to form liquid silicon and carbon monoxide gas. In an industrial preparation of silicon, 155.8 kg of silicon dioxide reacts with 78.3 kg of carbon to produce 66.1 kg of silicon. Determine the limiting reactant, theoretical yield of silicon, and the percent yield of silicon for this reaction.
