Question
- A. chemistry only: correct Unit 4.5 answer for Cells and batteries
- B. Incorrect: confuses chemistry only with a nearby Energy changes idea
- C. Incorrect: gives a general chemistry statement without linking to Cells and batteries
- D. Incorrect: reverses the energy-change relationship in 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 safe and careful use of liquids when investigating cells. (AT 6). This 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
Mixing up safe handling of acids and bases
Students often think that all liquids used in simple cells are harmless and can be handled without precautions, or they treat acidic and basic electrolytes the same way, ignoring the risk of splashes and corrosion.
Remind students that electrolytes can be acidic, basic or neutral, and that acidic or basic solutions can be corrosive or cause skin irritation. They should wear appropriate PPE (gloves, goggles, lab coat), use a fume hood or well‑ventilated area, and handle all liquids carefully to avoid splashes or spills. Emphasise that safety procedures are required for all liquids, not just for the cell’s operation.
