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 that rechargeable cells and batteries can be recharged because their chemical reactions are reversed by an external electrical current. 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 Rechargeability
Students often think that rechargeable cells can be recharged indefinitely without any loss of capacity.
Explain that while rechargeable cells can be recharged multiple times, their capacity decreases over time due to chemical degradation.
