The reaction between aluminium and copper(II) sulfate is: \(\mathrm{2Al + 3CuSO_4 \rightarrow Al_2(SO_4)_3 + 3Cu}\). If 5.0 g of aluminium are mixed with 10.0 g of copper(II) sulfate, (a) identify the limiting reagent, (b) calculate the mass of copper produced, and (c) calculate the mass of excess aluminium remaining after the reaction.

Answer Options

A. Limiting reagent: Al; copper produced ≈ 8.0 g; excess aluminium remaining ≈ 0.5 g.
B. Limiting reagent: CuSO₄; copper produced ≈ 9.5 g; excess aluminium remaining ≈ 4.5 g.
Correct Answer C. Limiting reagent: CuSO₄; copper produced ≈ 12.0 g; excess aluminium remaining ≈ 3.9 g.
D. Limiting reagent: CuSO₄; copper produced ≈ 15.0 g; excess aluminium remaining ≈ 2.0 g.
Correct Answer
C
Correct Option:
Limiting reagent: CuSO₄; copper produced ≈ 12.0 g; excess aluminium remaining ≈ 3.9 g.
