Question

If you start with 4 moles of iron and 3 moles of oxygen to produce iron oxide, what is the limiting reagent? (You will need to balance the equation first.) Fe + O2 -> Fe2O3
A. they are equal
B.Fe
C. O2
D.Fe2O3​

Answer 1

The correct statement regarding the limiting reactant for the reaction between 4 moles of iron and 3 moles of oxygen is: They are both equal. (Option A)

Balanced equation

We'll begin by writing the balanced equation for the reaction between iron and oxygen. This is given below:

4Fe + 3O₂ --> 2Fe₂O₃

SUMMARY

From the balanced equation above,

4 moles of Fe reacted with 3 moles of O₂

How to determine the limiting reactant

The limiting reactant is the reactant that is consumed completly in a chemical reaction.

The limiting reactant can be obtain as illustrated below:

From the balanced equation above,

4 moles of Fe reacted with 3 moles of O₂

From the illustration above, we can see that 3 moles of Fe required 4 moles of O₂ for complete reaction.

Thus, Fe and O₂ are both the limiting reactant.

Therefore, we can conclude that Fe and O₂ are equal
