उत्तर
| Sr. No. | Balanced chemical equation | Unbalanced chemical equation |
| 1. | A balanced chemical equation has an equal number of atoms of different elements on the sides of reactants and products. | An unbalanced chemical equation has an unequal number of atoms of one or more elements in the reaction. |
| 2. | In a balanced chemical equation, the sum of the masses of the reactants is equal to the sum of the masses of the products. | In an unbalanced chemical equation, the sum of the masses of the reactants is not equal to the sum of the masses of the products. |
| 3. | It obeys the law of conservation of mass. | It does not obey the law of conservation of mass. |
| 4. | Example: \[\ce{Zn + H2SO4 -> ZnSO4 + H2}\] | Example: \[\ce{H2 + O2 -> H2O}\] |
