Understanding the Chemical Reaction

In the given chemical reaction, 2 moles of aluminum (Al) react with 3 moles of iron oxide (FeO) to produce 3 moles of iron (Fe) and 1 mole of aluminum oxide (Al2O3). The balanced chemical equation is:

${ 2Al(s) + 3FeO(s) \rightarrow 3Fe(s) + Al_2O_3(s) }$

Determining the Number of Moles of Aluminum Oxide Produced

To calculate the number of moles of aluminum oxide (Al2O3) produced, we need to know the number of moles of iron (Fe) produced. According to the balanced chemical equation, 3 moles of Fe are produced for every 1 mole of Al2O3. Therefore, if 0.60 mol of Fe is produced, we can calculate the number of moles of Al2O3 produced as follows:

Step 1: Determine the mole ratio of Fe to Al2O3

From the balanced chemical equation, we can see that the mole ratio of Fe to Al2O3 is 3:1. This means that for every 3 moles of Fe, 1 mole of Al2O3 is produced.

Step 2: Calculate the number of moles of Al2O3 produced

To calculate the number of moles of Al2O3 produced, we can divide the number of moles of Fe produced (0.60 mol) by 3, since the mole ratio of Fe to Al2O3 is 3:1.

${ \text{Number of moles of Al}_2\text{O}_3 = \frac{\text{Number of moles of Fe}}{3} }$

${ \text{Number of moles of Al}_2\text{O}_3 = \frac{0.60 \text{ mol}}{3} }$

${ \text{Number of moles of Al}_2\text{O}_3 = 0.20 \text{ mol} }$

Conclusion

Therefore, the number of moles of aluminum oxide (Al2O3) produced when 0.60 mol of Fe is produced in the given reaction is 0.20 mol.

Answer

The correct answer is:

D. 0.20 mol

Additional Information

The balanced chemical equation for the reaction is: 2Al(s) + 3FeO(s) → 3Fe(s) + Al2O3(s)
The mole ratio of Fe to Al2O3 is 3:1.
To calculate the number of moles of Al2O3 produced, divide the number of moles of Fe produced by 3.
