Answer:

3 BaCl₂ + Al₂(SO₄)₃ ⇒ 2 AlCl₃ + 3 BaSO₄

A double displacement reaction

Explanation:

Let's consider the reaction between barium chloride and aluminum sulphate to give aluminum chloride and barium sulphate. This is a double displacement reaction. The unbalanced equation is:

BaCl₂ + Al₂(SO₄)₃ ⇒ AlCl₃ + BaSO₄

We will start balancing Al atoms by multiplying AlCl₃ by 2.

BaCl₂ + Al₂(SO₄)₃ ⇒ 2 AlCl₃ + BaSO₄

Next, we will balance Cl atoms by multiplying BaCl₂ by 3.

3 BaCl₂ + Al₂(SO₄)₃ ⇒ 2 AlCl₃ + BaSO₄

Finally, we get the balanced equation by multiplying BaSO₄ by 3.

3 BaCl₂ + Al₂(SO₄)₃ ⇒ 2 AlCl₃ + 3 BaSO₄
