The products of this reaction are a salt (barium sulphate), water and carbon dioxide.

Let's first write down the equation. Then we will balance it:

BaCO

Now, let's balance it. To balance any equation, you have to remember that the number of atoms of any element on one side have to be equal to the number of atoms of that element on the other side:

BaCO

Guess what, the equation is already balanced! You can count all the elements:

1 Ba

1 C

7 O

2 H

1 S

Let's first write down the equation. Then we will balance it:

BaCO

_{3}(s) + H_{2}SO_{4}(aq) --> BaSO_{4}(s) + H_{2}O (l) + CO_{2}(g)Now, let's balance it. To balance any equation, you have to remember that the number of atoms of any element on one side have to be equal to the number of atoms of that element on the other side:
