Question
- 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 metal oxides as bases
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 metal oxides as bases. 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 Metal Oxides
Students often confuse metal oxides with non-metal oxides, thinking both can act as bases.
Remember that metal oxides are bases, while non-metal oxides are typically acidic. Focus on the properties of metal oxides and their reactions with acids.
