Answer: FeCl3+O2-->Fe2O3+Cl2 is NOT balanced
Explanation:You first need to balance the equation. The balanced equation would be...
4FeCl3 + 3O2 ==> 2Fe2O3 + 6Cl2
moles FeCl3 present =4 moles
moles O2 present = 4 moles
Since the mole ration in the balanced equation is 4 FeCl3 : 3 O2, the limiting reactant will be FeCl3
moles Cl2 that can be produced = 4 moles FeCl3 x 6Cl2/4 moles FeCl3 = 6 moles Cl2
