The Hall-Heroult process for converting aluminum ore (Al_2O_3) to aluminum metal is based on the reaction of Al_2O_3 with carbon in molten cryolite (Na_3AlF_6). 2Al_2O_3 + 3C(s) + 2214.1 kJ rightarrow 4 Al(l) + 3 CO_2(g) where the state of matter for the Al_2O_3 is "in molten Na_3AIF_6" If an aluminum can has a mass of 14.07 g, how much thermal energy is required to recycle the aluminum in 36 cans? How much energy would be required to recover this amount of aluminum metal from Al_2O_3 using the Hall-Heroult process? 10384.129 kJ The energy required for the recycling is what percentage of that required for the Hall-Heroult process?
