The correct Answer is:
To determine which oxides can react with both acids and bases, we need to identify amphoteric oxides. Amphoteric oxides are those that can react with both acids and bases. Let's analyze the given options step by step. ### Step-by-Step Solution: 1. **Identify the Oxides**: The question requires us to evaluate different oxides to see if they are amphoteric. The oxides mentioned in the video are: - CaO (Calcium oxide) - Na2O2 (Sodium peroxide) - ZnO (Zinc oxide) - Mn3O4 (Manganese(II,III) oxide) 2. **Evaluate CaO**: - CaO is a metal oxide. - It is known to be a basic oxide because it reacts with acids to form salts and water. - **Conclusion**: CaO is not amphoteric. 3. **Evaluate Na2O2**: - Na2O2 is also a metal oxide and is a strong base. - It reacts with water to form NaOH and does not react with acids. - **Conclusion**: Na2O2 is not amphoteric. 4. **Evaluate ZnO**: - ZnO can react with acids (e.g., HCl) to form ZnCl2 and with bases (e.g., NaOH) to form Na2ZnO2. - This behavior indicates that ZnO can react with both acids and bases. - **Conclusion**: ZnO is amphoteric. 5. **Evaluate Mn3O4**: - Mn3O4 has manganese in oxidation states that can be basic. - It primarily behaves as a basic oxide and does not show amphoteric behavior. - **Conclusion**: Mn3O4 is not amphoteric. ### Final Answer: The oxide that can react with both acids and bases is **ZnO (Zinc oxide)**, which is option C. ---
