Question 6 (5 points) (05.05 MC)
The following data was collected when a reaction was performed experimentally in the laboratory

Determine the maximum amount of Fe that was produced during the experiment. Explain how you determined this amount.

5 moles

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

Fe₂O₃ + 2Al —> Al₂O₃ + 2Fe

From the balanced equation above,

1 mole of Fe₂O₃ reacted with 2 moles of Al to produce 2 moles of Fe.

Next, we shall determine the limiting reactant. This can be obtained as follow:

From the balanced equation above,

1 mole of Fe₂O₃ reacted with 2 moles of Al.

Therefore, 3 moles of Fe₂O₃ will react with = 3 × 2 = 6 moles of Al.

From the calculation made above, we can see clearly that it will require a higher amount (i.e 6 moles) of Al than what was given (i.e 5 moles) to completely react with 3 moles of Fe₂O₃.

Thus, Al is the limiting reactant and Fe₂O₃ is the excess reactant.

Finally, we shall determine the maximum amount of Fe produced.

In this case, the limiting reactant will be used because all of it is consumed by the reaction.

The limiting reactant is Al and maximum amount of Fe produced can be obtained as follow:

From the balanced equation above,

2 moles of Al reacted to produce 2 moles of Fe.

Therefore, 5 moles of Al will also react to produce 5 moles of Fe.

Thus, the maximum amount of Fe produced was 5 moles.

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
