Answer
Difference between a balanced and a skeletal chemical equation :
| Balanced chemical equation | Skeletal chemical equation |
|---|---|
| In balanced chemical equation the total number of atoms on the reactant side as well as the product side are equal. | In skeletal chemical equation the total number of atoms on the reactant side and product side are not equal. |
| Example: Zn + H2SO4 ⟶ ZnSO4 + H2 | Example: H2 + O2 ⟶ H2O |
