Balanced Chemical Equation for the Thermal Decomposition of Calcium Carbonate

The thermal decomposition of calcium carbonate results in the formation of calcium oxide and carbon dioxide gas. The balanced chemical equation for this reaction can be written as follows:

CaCO3(s) → CaO(s) + CO2(g)

Explanation

The reactant in this equation is calcium carbonate (CaCO3), which is a solid. When it is heated, it undergoes thermal decomposition, meaning it breaks down into simpler substances. The products of this reaction are calcium oxide (CaO), also known as quicklime, and carbon dioxide gas (CO2).

The balanced chemical equation shows that one molecule of calcium carbonate yields one molecule of calcium oxide and one molecule of carbon dioxide gas. This means that the number of atoms of each element is conserved in the reaction. The equation is balanced because the number of atoms of each element on both sides of the equation is equal.

Importance of Balanced Chemical Equations

Balanced chemical equations are important because they provide a quantitative description of chemical reactions. They allow us to predict the amount of reactants needed to produce a certain amount of product, or to determine the amount of product that will be formed from a given amount of reactant.

In addition, balanced chemical equations provide information about the stoichiometry, or the ratio of reactants and products in a reaction. This information is crucial for understanding the fundamental principles of chemistry and for carrying out chemical calculations.

Conclusion

In summary, the balanced chemical equation for the thermal decomposition of calcium carbonate is CaCO3(s) → CaO(s) + CO2(g). This equation shows that one molecule of calcium carbonate yields one molecule of calcium oxide and one molecule of carbon dioxide gas. Balanced chemical equations are important for predicting the amount of reactants and products in a reaction, as well as for understanding the stoichiometry of chemical reactions.

Yes, Reactant side= Product side, that's why it is a balanced equation.....
