Complete the following
2Al2O3+3C→4A+3B. A & B are as follows.
Alumina reacts with carbon or coke to form Aluminium and carbon dioxide.
This is not used to extract Aluminum as the (very high) temperature makes the process economically unviable. Also, at such elevated temperatures (2000 0C), Aluminum could react with Coke (carbon) to form Aluminum Carbide.
