___Fe2O3 + ___C --> ___Fe + ___ C03 balanced
SashulF [63]

Answer:

Fe2O3 + C → 2Fe + CO3

Explanation:

The unbalanced equation given in this question is as follows:

Fe2O3 + C → Fe + C03

To balance this equation, one should ensure that the number of atoms of each element on both sides of the equation is equal. The balanced equation is as follows;

Fe2O3 + C → 2Fe + CO3

N.B, there are;

- 2atoms of Fe on both sides

- 1 atom of C on both sides

- 3 moles of O on both sides
