It takes 45.0 kWh (kilowatt-hours) of electrical energy to produce 3.00 kg aluminum metal from aluminum oxide by the Hall-Heroult process. What amount of energy is necessary to melt 3.00 kg aluminum metal? The enthalpy of fusion for aluminum metal is 10.7 kJ/mol (1 watt = 1 J/s).
The aluminum in bauxite must be separated from its oxygen and hydrogen compounds and then further purified to produce the pure metal that we are all familiar with. A large amount of electrical energy is required to obtain pure aluminum metal. For example, processing 1 kg of aluminum from bauxite ore consumes 30 kwh of electricity. One of the most common uses of aluminum is for beverage cans. A standard size aluminum beverage can weigh 13 grams. Last year, the...
When exposed to air, aluminum metal, Al, reacts with oxygen, O2, to produce a protective coating of aluminum oxide, Al2O3, which prevents the aluminum from rusting underneath. The balanced reaction is shown here: 4Al+3O2→2Al2O3 a. What is the theoretical yield of aluminum oxide if 1.60 mol of aluminum metal is exposed to 1.50 mol of oxygen?
Aluminum metal is produced by electrolysis from molten aluminum oxide. The cell operates at 8.0V with a current of 4.0 *104 amps. How many kilowatt hours of electricity is used to produce 1.00kg of aluminum metal?
