Question 5

What is the process?

Answer 5

Coke is burned to very high temperatures, this is when is reacts with oxygen; C +O2===> CO2
Then the carbon dioxide reacts with more carbon to form carbon monoxide; C+CO2===>2CO
Carbon monoxide is the reducing agent (causes another substance to lose oxygen).
Fe2O3 + 3CO ===> 2Fe + 3CO2.

Question 6

Equations in order.

Answer 6

C + O2 ===> CO2
C + CO2 ===> 2CO
Fe2O3 + 3CO ===> 2Fe +3CO2.
