Balanced Chemical Equation – Solution
2CaO + 2Cl2 → Ca(OCl)2 + CaCl2
The coefficients show the number of particles (atoms or molecules), and the indices show the number of atoms that make up the molecule. New substances are formed as a result of the rearrangement of the original atoms. As a result of a chemical reaction, atoms of chemical elements do not disappear anywhere and new ones do not appear, their number remains unchanged – this follows from the law of conservation of mass of substances.
Chemical Reaction Information
Calcium Oxide + Dichlorine = Calcium Hypochlorite + Calcium Chloride
This is an oxidation-reduction (redox) reaction. Cl2 is both an oxidizing and a reducing agent (disproportionation (dismutation)).
- 2 Cl0 – 2 e– → 2 ClI (oxidation)
- 2 Cl0 + 2 e– → 2 Cl-I (reduction)
Reaction Type
Double Displacement (Metathesis)
Substances that react are called starting materials or reactants. The substances that form as a result are called reaction products.

| CaO + Cl2 = CaCl2 + O |
| CaO + Cl2 + NH3 = CaCl2 + H2O + N2 |
| CaO + Cl2 = CaCl2 + Ca(ClO)2 |
| Cl2 + CaO → CaOCl2 |
| CaO + Cl2 = CaCl + O2 |
| CaO + Cl2 = CaCl + O |
| Cl2 + CaO → O2 + CaCl2 |
| Ca(OCl)2 + CaCl2 + CO2 = CaCO3 + Cl2 |
| Ca(OCl)2 + CaCl2 + H2O = Ca(OH)2 + Cl2 |
