Balance the following chemical equation
Calcium hydroxide + carbon dioxide -calcium carbonate + water
Step 1: Write the chemical reaction into equation
Ca(OH)2+CO2⟶CaCO3+H2O
Step 2: The total number of atoms of each element on the reactant side and the product side must be compared.
Elements | Reactant side | Product side |
Ca | 1 | 1 |
O | 4 | 4 |
H | 2 | 2 |
C | 1 | 1 |
Hence the reaction is balanced.
Balanced chemical equation is : Ca(OH)2+CO2⟶CaCO3+H2O
