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 batteries as two or more cells connected together in series. 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 Battery Structure

Students often think that batteries are single cells rather than a combination of multiple cells connected together.

Emphasize that batteries consist of two or more cells connected in series, which work together to produce electricity.
