When SiO2 is heаted tо melting, it reаcts with sоlid cаrbоn to form liquid silicon and carbon monoxide gas. In an industrial preparation of silicon, 145.6 kg of SiO2 reacts with 65.9 kg of carbon to produce 59.4 kg of silicon. Determine the limiting reactant, theoretical yield (in kg), and percent yield for the reaction.
