Answer 3

The chemical equation you provided represents a chemical reaction between calcium hydroxide (Ca(OH)2) and carbon dioxide (CO2) to form water (H2O) and calcium carbonate (CaCO3). Let's balance the equation:

Ca(OH)2 + CO2 → H2O + CaCO3

To balance the equation, we need to make sure that the same number of atoms of each element are present on both sides of the equation. Let's go step by step:

1. Calcium (Ca): There is 1 Ca atom on the left (in Ca(OH)2) and 1 Ca atom on the right (in CaCO3). This is already balanced.

2. Hydrogen (H): There are 2 H atoms on the left (in Ca(OH)2) and 2 H atoms on the right (in H2O). This is already balanced.

3. Oxygen (O): There are 2 O atoms in Ca(OH)2, and 3 O atoms in CO2 and CaCO3 combined. To balance O atoms, we need to have 2 O atoms on the right side. The only way to achieve this is by having 2 H2O molecules on the right side.

The balanced equation is:

Ca(OH)2 + CO2 → 2H2O + CaCO3

Now, the equation is balanced, and it shows that calcium hydroxide reacts with carbon dioxide to produce water and calcium carbonate.
