Answer:-
3 C + Fe2O3 --> 2 Fe + 3 CO
3 : 2 ratio
Explanation:-
The chemical formula of Iron Oxide = Fe2O3
The symbol for Carbon = C
The symbol for Iron = Fe
The equation for this reaction becomes
C + Fe2O3 --> Fe + CO
On the left side there are 2 Fe
To make 2 Fe on right side we multiply Fe by 2.
C+ Fe2O3 --> 2 Fe + CO
There are 3 O on the left side. To make 3 O on right side we multiply CO by 3.
C + Fe2O3 --> 2 Fe + 3 CO
Now we have 3 C on the right side. To make 3 C on the left we multiply C by 3.
3 C + Fe2O3 --> 2 Fe + 3 CO
Thus balanced chemical equation for this reaction is
3 C + Fe2O3 --> 2 Fe + 3 CO
So in the balanced reaction we have 3 C and 2 Fe.
∴ The ratio of C to Fe is 3 : 2
