a. Estimate the amount of energy needed to obtain 1kg metallurgical silicon. b. Can this reaction be powered by solar energy? If a solar panel produces 300W of power, how many panels are needed for the reaction to be complete in 3 hours? Remember that: - Silicon dioxide ( SiO2) has a heat of fusion of 730J/kg.K - Silicon dioxide covalent bond energy: 621.7kJ/mol - The molar mass of silicon dioxide is 60.08g/mol - 1kWW is 3.610J
