Question
Complete the following
2Al2O3+3C→4A+3B. A & B are as follows.
2Al2O3+3C→4A+3B. A & B are as follows.
Answer: Option C
:
C
Alumina reacts with carbon or coke to form Aluminium and carbon dioxide.
2Al2O3+3C→4Al+3CO2
This is not used to extract aluminium as the (very high) temperature makes the process economically unviable. Also, at such elevated temperatures (2000 0C), aluminium could react with coke (carbon) to form aluminium carbide.
