Q1.
The overall equation for the electrolysis of aluminium oxide is:
2 Al2O3 → 4 Al + 3 O2
Calculate the mass of oxygen produced when 2000 kg of aluminium oxide is completely electrolysed.
Relative atomic masses (Ar): O = 16 Al = 27 __________________________________________________________ __________________________________________________________ __________________________________________________________ __________________________________________________________ __________________________________________________________
__________________________________________________________ __________________________________________________________ __________________________________________________________
Mass of oxygen = __________________________ kg (4)
