2 Fe2O3 + 3 C→ 4 Fe + 3 CO3
The reactant and products in this chemical equation is as below
Reactant
Fe2O3
C
Product
Fe
CO2
Explanation
A chemical reaction involve rearrangement reactants to form products.
Reactants are written on the left side of a chemical reaction while products are written on the right hand side of chemical reaction.
Since Fe2O3 and C are on left side of chemical reaction they are the reactants.
Fe and CO2 are on the right side of chemical reaction they are the products.
