Question Question 10
Differentiate between:
(a) Reactants and Products
(b) A balanced and an unbalanced chemical equation
(a) Differences between Reactants and Products
| Reactants | Products |
|---|---|
| The substances that are used as the starting material and which react with one another are called reactants. | The substances which are formed as a result of the reaction are called products. |
| Reactants are written on the left hand side of the equation. | Products are written on the right hand side of the equation. |
| In equation C + O2 ⟶ CO2, C and O2 are reactants. | In equation C + O2 ⟶ CO2, CO2 is product. |
(b) Differences between a balanced and an unbalanced chemical equation
| Balanced chemical equation | Unbalanced chemical equation |
|---|---|
| In balanced chemical equation the total number of atoms on the reactant side as well as the product side are equal. | In unbalanced 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 |
