    1. 2Fe + Cl2 ➡ 2FeCl

    2. 4Fe + 3O2➡ 2Fe2O3

    Explanation:

    1).) Fe + Cl2 → FeCl

    Fe = 1 Cl=2 ➡ Fe = 1 Cl = 1

    ) Fe + Cl ➡ 2FeCl

    Fe=1 Cl = 2 ➡ Fe=2 Cl=2

    2Fe + Cl ➡ 2FeCl

    Fe=2 Cl=2 ➡ Fe=2 Cl = 2

    2).) Fe + O2 →Fe2O3

    Fe=1 O = 2 ➡Fe = 2 O = 3

    ) Fe + O2 ➡2Fe2O3

    Fe=1 O=2 ➡Fe=4 O=6

    ) 4Fe + O2 ➡2Fe2O3

    Fe = 4 O = 2 ➡Fe = 4 O = 6

    ) 4Fe + 3O2 ➡2Fe2O3

    Fe = 4 O = 6➡ Fe = 4 O = 6
