- A. By whether it contains a metal or a non-metal. - correct reaction focus for metal oxide
- B. Wrong reaction focus: confuses metal oxide with a nearby Unit 4.4 chemical change idea
- C. Wrong particle check: uses the wrong ion, electrode, acid-base term, or product for Metal oxides
- D. Wrong reaction link: does not support Describe non-metal oxides as acidic
Answer
The correct option is By whether it contains a metal or a non-metal. - correct reaction focus for metal oxide.
Explanation
The correct option is "By whether it contains a metal or a non-metal. - correct reaction focus for metal oxide" because it supports the approved learning objective: Describe non-metal oxides as acidic. The other options are incorrect or weaker because they are vague, use the wrong Chemistry context, or do not clearly explain the answer for Metal oxides.
Common mistake
Misunderstanding Non-Metal Oxides
Students often confuse non-metal oxides with metal oxides, thinking they are basic instead of acidic.
Remember that non-metal oxides are acidic, while metal oxides are typically basic. Focus on the type of element in the oxide to determine its properties.
