The balanced chemical equation is Ca(OH)2 + CO2 → CaCO3 + H2O. To balance the chemical equation for the reaction between calcium hydroxide (Ca(OH)2) and carbon dioxide (CO2) to form calcium carbonate (CaCO3) and water (H2O), adjust the coefficients as follows: Ca(OH)2 + CO2 → CaCO3 + H2O

## What is a Balanced Chemical Equation?

A balanced chemical equation represents a chemical reaction where the number of atoms of each element is equal on both sides. It follows the law of conservation of mass, which states that matter is neither created nor destroyed in a chemical reaction. The reactants are written on the left side, the products on the right side, and an arrow indicates the direction of the reaction.

Coefficients are added to the formulas to balance the equation and reflect the relative amounts of substances involved. Balancing ensures that the same number of atoms of each element exists before and after the reaction. Balanced chemical equations are crucial for accurately representing chemical reactions and performing stoichiometric calculations.

For Example: 2H2 + O2 → 2H2O

Solution

The balanced chemical equation for the reaction between calcium hydroxide (Ca(OH)2) and carbon dioxide (CO2) to form calcium carbonate (CaCO3) and water (H2O) is as follows:

Ca(OH)2 + CO2 → CaCO3 + H2O

Step 1: Balance the calcium (Ca) atoms:

Ca(OH)2 + CO2 → 1CaCO3 + H2O

Step 2: Balance the carbon (C) atoms:

Ca(OH)2 + CO2 → 1CaCO3 + H2O

Step 3: Balance the hydrogen (H) atoms:

Ca(OH)2 + CO2 → 1CaCO3 + H2O

Step 4: Balance the oxygen (O) atoms:

Ca(OH)2 + CO2 → 1CaCO3 + H2O

Now, the equation is balanced with an equal number of atoms on both sides. The final balanced chemical equation is:

Ca(OH)2 + CO2 → CaCO3 + H2O

Summary

## Balance the following chemical equation: Calcium Hydroxide + Carbon Dioxide→Calcium Carbonate + Water

The balanced chemical equation for the reaction between calcium hydroxide (Ca(OH)2) and carbon dioxide (CO2) to form calcium carbonate (CaCO3) and water (H2O) can be summarized as Ca(OH)2 + CO2 → CaCO3 + H2O
