The answer is [tex]2Fe_2O_3 + 3C -> 3Fe + 3CO_2[/tex]

You must make sure each reactant has the same amount of subscripts on both sides of the equation.

Answer:

2Fe₂O₃ + 3C → 4Fe + 3CO₂

Explanation:

An equation is said to be balanced if there are equal number of atoms of one type on the reactants as well as the product side. The given equation is:

Fe₂O₃ + C → Fe + CO₂

   #  Reactants                         # Products

  Fe = 2                                       Fe = 1

  O = 3                                         O = 2

  C = 1                                          C = 1

The equation is not balanced as there are different number of atoms of Fe and O on either side. In order to balance it, multiply Fe2O3 by 2, C by 3, Fe by 4 and CO2 by 3 to get:

2Fe₂O₃ + 3C → 4Fe + 3CO₂
