Dr. Richard W.
Answer:

Answer 1) Balance the Chlorine (Cl) (note that 2 x 3 = 3 x 2): 2FeCl3 + MgO ---> Fe2O3 + 3MgCl2 The Iron (Fe) also gets balanced in this step. 2) Pick either the Oxygen (O) or the Magnesium (Mg) to balance next: 2FeCl3 + 3MgO ---> Fe2O3 + 3MgCl2 The other element (Mg or O, depending on which one you picked) also gets balanced in this step.
