The theoretical yield of iron metal is 42.3 g

The equation for the reaction is:

Fe₂O₃ + 3CO → 2Fe + 3CO₂

Since, all of the carbon monoxide was consumed during the reaction, then carbon monoxide is the limiting reactant

Thus, iron (III) oxide is the excess reactant

<h3>Stoichiometry </h3>

From the question, we are to determine the theoretical yield of iron metal

First, we will write the balanced chemical equation for the reaction

The balanced chemical equation for the reaction is

Fe₂O₃ + 3CO → 2Fe + 3CO₂

This means

1 mole of iron(III) oxide reacts with 3 moles of carbon monoxide to produce 2 moles of iron metal and 3 moles of carbon dioxide gas.

Now, to determine the theoretical yield of iron metal

First, we will determine the number of moles of each reactant present

  • For iron(III) oxide

Mass = 75.0 grams

Molar mass = 159.69 g/mol

Using the formula,

Number \ of \ moles = \frac{Mass}{Molar\ mass}

Then,

Number of mole of Fe₂O₃ present = \frac{75.0}{159.69}

Number of mole of Fe₂O₃ present = 0.46966 mole

  • For carbon monoxide

Mass = 50.0 g

Molar mass = 44.01 g

Then,

Number of moles of CO₂ present = \frac{50.0}{44.01}

Number of moles of CO₂ present = 1.136105 moles

Now,

If 1 mole of iron(III) oxide reacts with 3 moles of carbon monoxide to produce 2 moles of iron metal

Then,

0.378702 mole of iron(III) oxide will react with 1.136105 moles of carbon monoxide to produce 0.757403 moles of iron metal

Therefore, the number of moles of iron metal that would be produced is 0.757403 moles

Now, for the mass of the iron metal

Using the formula

Mass = Number of moles × Molar mass

Atomic mass of iron metal = 55.845 g/mol

Then,

Mass of iron metal that would be produced = 0.757403 × 55.845

Mass of iron metal that would be produced = 42.29717 g

Mass of iron metal that would be produced ≅ 42.3 g

Hence, the theoretical yield of iron metal is 42.3 g

The equation for the reaction is:

Fe₂O₃ + 3CO → 2Fe + 3CO₂

Since, all of the carbon monoxide was consumed during the reaction, then carbon monoxide is the limiting reactant

Thus, iron (III) oxide is the excess reactant

In two or more complete sentences explain how to balance the chemical equation and classify its reaction type
Dafna11 [192]

Answer:

Hi! In this case, the reactioncan be correctly balance according to this: 2Al(s) + 3CuSO4(aq) –> Al2(SO4)3(aq) + 3Cu(s).

Explanation:

In this particulary reaction,two semi-reactions happens.

One involving the metallic aluminum that suffers an oxidation reaction:

Al (s) -> Al3 + (aq) + 3e–

and another is a reduction reaction involving copper;

2e– + Cu2 + (aq) -> Cu (s)
