The most useful ore of aluminum is bauxite, in which Al is present as hydrated oxides, Al₂O₃ · xH₂O. The number of kilowatt-hours of electricity required to produce 3.00 kg of aluminum from electrolysis of compounds from bauxite is ________ when the applied emf is 4.50 V.

Question

Quizplus · Accepted Answer

To calculate the electricity required, use the formula: Energy (kWh) = (moles of Al * Faraday's constant * voltage) / (3600 * 1000). For 3 kg of Al, calculate moles, then use the given voltage to find the energy in kWh.
