Chemical cells and fuel cells (chemistry only)
Question
- A. chemistry only: correct Unit 4.5 answer for Cells and batteries
- B. Incorrect exam-check: gives a memorised phrase without subtopic detail
- C. Incorrect exam-check: omits the key Energy changes vocabulary
- D. Incorrect exam-check: answers a different objective from Chemical cells and fuel cells (chemistry only)
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) Describe that cells contain chemicals that react to produce electricity. This exam-check 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 Cell Composition
Students often think that cells only contain metals and do not recognize the role of electrolytes in producing electricity.
Emphasize that cells consist of two different metals and an electrolyte, which is crucial for the chemical reactions that generate electricity.
