The correct Answer is:
To solve the question regarding the incorrect pairing between compounds and mixtures, we will analyze each statement provided in the question step by step. ### Step 1: Analyze the first pairing **Pairing:** Mixture - Physical union; Compound - Chemical union **Analysis:** This statement is correct. A mixture is formed by the physical combination of substances, while a compound is formed through a chemical reaction where elements combine in a specific ratio. **Conclusion:** This is not the incorrect pairing. ### Step 2: Analyze the second pairing **Pairing:** Mixture - No new substances are formed; Compound - New substances are formed **Analysis:** This statement is also correct. In a mixture, the original substances retain their properties and no new substances are formed. In a compound, the elements react chemically to form a new substance with different properties. **Conclusion:** This is not the incorrect pairing. ### Step 3: Analyze the third pairing **Pairing:** Mixture - Can be separated by physical means; Compound - Can be separated by physical means **Analysis:** This statement is incorrect. Mixtures can indeed be separated by physical means (e.g., filtration, distillation), but compounds cannot be separated by physical means; they require chemical methods to break down into their constituent elements. **Conclusion:** This is the incorrect pairing. ### Step 4: Analyze the fourth pairing **Pairing:** Mixture - Elements form no definite proportion; Compound - Elements form definite proportions **Analysis:** This statement is correct. In a mixture, the components can be present in any proportion, while in a compound, the elements combine in a fixed ratio (e.g., water is always H2O). **Conclusion:** This is not the incorrect pairing. ### Final Answer The incorrect pairing is: **Mixture - Can be separated by physical means; Compound - Can be separated by physical means.** ---
