Answer:
Fe2O3 + 3H2 => 2Fe + 3H2O
Step-by-step explanation:
A chemical equation is defined as the symbolic representation of a chemical reaction and in a balanced chemical reaction, the number of atoms of the reagents must be equal to the number of atoms of the products.
The balanced chemical reaction between solid iron (III) oxide reacts with hydrogen gas would be:
Fe2O3 + 3H2 = 2Fe + 3H2O
