    3C + 2Fe ₂ O ₃ → 3CO ₂ + 4Fe

    Explanation:

    C + Fe ₂ O ₃ → CO ₂ + Fe

    Left Side

    C = 1

    Fe = 2

    O = 3

    Right Side

    C = 1

    Fe = 1

    O = 2

    So we can see that while Carbon is balanced Fe and O are not.

    We then attempt to balance the equation by balancing the Oxygen.

    C + 2Fe ₂ O ₃ → 3CO ₂ + Fe

    Left Side

    C = 1

    Fe = 4

    O = 6

    Right Side

    C = 3

    Fe = 1

    O = 6

    Oxygen is now balanced but C and Fe are not, though this is an easy fix as each are independent on each side of the equation.

    3C + 2Fe ₂ O ₃ → 3CO ₂ + 4Fe

    Left Side

    C = 3

    Fe = 4

    O = 6

    Right Side

    C = 3

    Fe = 4

    O = 6
