Question
- A. chemistry only: correct Unit 4.5 answer for Cells and batteries
- B. Incorrect example: uses a device, reaction, or diagram not linked to chemistry only
- C. Incorrect example: gives evidence without explaining the energy transfer
- D. Incorrect example: describes a broad practical skill instead of the objective
Answer
The correct option is chemistry only: correct Unit 4.5 answer for Cells and batteries.
Explanation
The correct option is chemistry only: correct Unit 4.5 answer for Cells and batteries. It directly supports the approved learning objective to (chemistry only) Explain why two different electrodes are needed in a simple chemical cell. This diagram version keeps the answer anchored to Cells and batteries within Chemical cells and fuel cells (chemistry only), and avoids mixing energy transfer, reaction profiles, activation energy, chemical cells, fuel cells, exothermic reactions and endothermic reactions unless the objective names them.
Common mistake
Misunderstanding Electrode Function
Students often think that both electrodes in a simple chemical cell can be the same material, believing this would not affect the cell's function.
Emphasize that different electrodes are needed to create a potential difference, as they must have different reactivities to drive the electrochemical reactions.
