Aluminum Metal Is Refined from Bauxite Ore in a Very

Aluminum metal is refined from bauxite ore in a very energy-intensive process using the Hall process, which requires electrolysis of aluminum oxide, Al₂O₃, in molten cryolyte at more than 1012°C.In an industrial electrolysis cell, 1900 kg of aluminum oxide was reduced with a current of 1500 amps.How long did it take to reduce all the reactant to aluminum metal?

B) 2.0 *10³ hr
C) 330 hr
D) 4.0 * 10³ hr
E) 660 hr
