Question

What is the balanced equation when aluminum reacts with copper(II) sulfate?

a. Al + Cu₂S → Al2S + Cu
b. 2Al + 3CuSO₄ → Al₂(SO₄)₃ + 3Cu
c. Al + CuSO4 → AlSO₄ + Cu
d. 2Al + Cu₂SO₄ → Al₂SO₄ + 2Cu

Answer 1

The balanced equation when aluminum reacts with copper(II) sulfate is 2Al + 3CuSO₄ → Al₂(SO₄)₃ + 3Cu.

Step-by-step explanation:

The balanced equation when aluminum reacts with copper(II) sulfate is:

2Al + 3CuSO₄ → Al₂(SO₄)₃ + 3Cu

Here's how to balance the equation:

1. First, check that the elements and charges are properly represented in the reactants and products.
2. Next, balance the sulfuric acid (H₂SO₄) by changing its coefficient from 1 to 3.
3. Then, balance the aluminum (Al) by changing its coefficient from 1 to 2.
4. Finally, double-check that all elements are balanced and all coefficients are in the simplest whole-number ratio.
