protons than atoms of many other metals.
Explanation:
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
