Question

Which is the balanced single displacement reaction between Aluminum (Al³⁺) and Copper Sulfate (Cu²⁺(SO₄)₂²⁻)?

Options:
A. Al + CuSO₄ → Cu + AlSO₄
B. 2Al + 3CuSO₄ → 3Cu + Al₂(SO₄)₃
C. Al₂ + Cu(SO₄)₃ → Cu + Al₂(SO₄)₃
D. Al + CuSO₄ → Cu + Al₂(SO₄)₃

Answer 1

The balanced single displacement reaction between Aluminum and Copper Sulfate is 2Al + 3CuSO4 → 3Cu + Al2(SO4)3, which corresponds to option B.

Step-by-step explanation:

Single Displacement Reaction between Aluminum and Copper Sulfate

In a single displacement reaction, aluminum (Al) is more reactive than copper (Cu), so it will replace copper in the compound copper sulfate (CuSO4). The formula for copper sulfate is actually CuSO4, not Cu2+(SO4)22- as mentioned in the question, presuming a typo. The balanced single displacement reaction is:

2Al + 3CuSO4 → 3Cu + Al2(SO4)3

Every atom on the reactant side is accounted for on the product side, keeping mass conserved.
