Answer:
FeCl3
Step-by-step explanation:
We'll begin by writing the balanced equation for the reaction. This is shown below:
4FeCl3 + 3O2 —> 2Fe2O3 + 6Cl2
Thus, the limiting reactant can be obtained as follow:
From the balanced equation above,
4 moles of FeCl3 reacted with 3 moles of O2.
Therefore, 8 moles of FeCl3 will react with = (8 x 3)/4 = 6 moles of O2.
From the calculation made above, we can see that a lesser amount of O2 is needed to react completely with 8 moles of FeCl3. Therefore, FeCl3 is the limiting reactant.
