Electronic Configuration of Bromine

Q. Balance the equation: Ca(OH)2+ CO2CaCO3+ H2O

The given chemical equation is Ca(OH)2+ CO2CaCO3+ H2O

Calcium Hydroxide + Carbon-dioxide→ Calcium Carbonate + Water

Balanced chemical equation: Ca(OH)2+ CO2CaCO3+ H2O

Note: The given equation is already balanced.

Information provided by the equation:

• This is an acid-base (neutralization) reaction: Ca(OH)2 is a base, CO2 is an acid.
• When calcium hydroxide combines with carbon dioxide gas, an insoluble milky white precipitate of calcium carbonate and water is formed. A twofold displacement reaction follows the reaction.

Balanced Chemical Equation:

A chemical equation is a representation of a chemical process in the form of substances. A balanced chemical equation is one in which the number of atoms in all of the molecules is equal on both sides of the equation.

• The balancing of a chemical equation is governed by the Law of Conservation of Mass.
• This law asserts that mass cannot be created or destroyed in a chemical reaction, and that the total mass of elements or molecules present on the reactant side must equal the total mass of elements or molecules present on the product side.
• The law of conservation does not apply if the chemical equation is not balanced.
