limiting reagent

Many computer chips are manufactured from silicon, which occurs in nature as SiO2. When SiO2 is heated to melting, it reacts with solid carbon to form liquid silicon and carbon monoxide gas. In an industrial preparation of silicon, 154.9 kg of SiO2is allowed to react with 79.3 kg of carbon to produce 66.2 kg of silicon. Determine the limiting reactant for the reaction. Determine the theoretical yield for the reaction. Express your answer using four significant figures.   Determine the percent yield for the reaction.
