9. Find the energy required produce 1kg of Al from native Al2O3 and compare this with the energy required to melt 1kg of aluminum in a recycling plant.
First look at the chemical equation:
2Al2O3 --> 4Al + 3O2
If we have 1Kg of Al we can find the number of moles of Al through ...
The solution discusses the energy required to produce 1 kg of Al.
