Answer:

The answer to your question is:

Step-by-step explanation:

Reaction

Na₂SO₄ (aq) + CaCl₂(aq) ⇒ CaSO₄(s) + NaCl(aq)

2 ------------- Na --------------- 1

1 ------------ S -------------- 1

1 ---------- Ca -------------- 1

2 ------------ Cl -------------- 1

1 ------------ O -------------- 1

Then, there are less Na and Cl in the products, so,

Na₂SO₄ (aq) + CaCl₂(aq) ⇒ CaSO₄(s) + 2 NaCl(aq)

2 ------------- Na --------------- 2

1 ------------ S -------------- 1

1 ---------- Ca -------------- 1

2 ------------ Cl -------------- 2

1 ------------ O -------------- 1

Now, the reaction is balanced.
