Answer:

2Al2O3 (l) ---> 4Al (l) + 3O2 (g)

Explanation:

The reaction is the electrolysis of aluminium oxide. It decomposes aluminium oxide (Al2O3) into aluminium metal (Al) and Oxygen (O2). In this process, aluminium oxide is molten (liquid state) so that ions can move to complete the electricity circuit.

Al2O3 (l) ---> Al (l) + O2 (g)

Balance the equation:

2Al2O3 (l) ---> 4Al (l) + 3O2 (g)
