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:

Step 1:

The balanced equation for the reaction.

Fe2O3 + 2Al —> Al2O3 + 2Fe

Step 2:

Determination of the limiting reactant.

From the balanced equation above,

1 mole of Fe2O3 reacted with 2 moles of Al.

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

We can see that the amount of Al required to react with 3 moles of Fe2O3 is higher that the amount given. Therefore, Al is the limiting reactant and Fe2O3 is the excess reactant.

Step 3:

Determination of the maximum amount of Fe produced during the reaction.

The limiting reactant is always use to determine the maximum yield of the reaction because all of it is used up in the reaction.

The limiting reactant is Al.

From the balanced equation above,

2 moles of Al produced 2 moles of Fe.

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

The maximum amount of Fe produced by the reaction is 5 moles

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.
