Ca(OH)2+CO3

To balance the chemical equation given as Ca(OH)2 + CO3, we need to first determine the correct formula for the carbonate ion. The formula for the carbonate ion is CO3^2-. So, the balanced chemical equation should be:

Ca(OH)2 + CO2 → CaCO3 + H2O

This balanced equation represents the reaction between calcium hydroxide and carbon dioxide to form calcium carbonate and water.
