The correct Answer is:
To solve the matching question, we will analyze each process and determine the corresponding type of reaction. Here’s the step-by-step solution: ### Step 1: Analyze the First Process - **Process**: Crumbling of chalk when heated - **Analysis**: When chalk (calcium carbonate) is heated, it decomposes into calcium oxide and carbon dioxide. This is a decomposition reaction. - **Match**: 1 → (b) Decomposition ### Step 2: Analyze the Second Process - **Process**: Iron displacing copper from copper sulphate - **Analysis**: In this reaction, iron displaces copper from copper sulphate solution, which is characteristic of a single displacement reaction. - **Match**: 2 → (a) Single displacement ### Step 3: Analyze the Third Process - **Process**: Formation of an insoluble compound - **Analysis**: The formation of an insoluble compound typically occurs in a precipitation reaction, where two soluble reactants form an insoluble product. - **Match**: 3 → (e) Precipitation ### Step 4: Analyze the Fourth Process - **Process**: Energy released is more than the energy absorbed - **Analysis**: This describes an exothermic reaction, where the total energy released during the reaction is greater than the energy absorbed. - **Match**: 4 → (c) Exothermic ### Step 5: Analyze the Fifth Process - **Process**: Dissolution of ammonium chloride (NH₄Cl) in water - **Analysis**: The dissolution of ammonium chloride in water is an endothermic process because it absorbs heat from the surroundings. - **Match**: 5 → (d) Endothermic ### Final Matches: 1. Crumbling of chalk when heated → (b) Decomposition 2. Iron displacing copper from copper sulphate → (a) Single displacement 3. Formation of an insoluble compound → (e) Precipitation 4. Energy released is more than the energy absorbed → (c) Exothermic 5. Dissolution of ammonium chloride in water → (d) Endothermic ### Summary of Matches: - 1 → (b) - 2 → (a) - 3 → (e) - 4 → (c) - 5 → (d)
