Question
- A. state: correct Unit 4.5 answer for Energy transfer during exothermic and endothermic reactions
- 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 Exothermic and endothermic reactions
Answer
The correct option is state: correct Unit 4.5 answer for Energy transfer during exothermic and endothermic reactions.
Explanation
The correct option is state: correct Unit 4.5 answer for Energy transfer during exothermic and endothermic reactions. It directly supports the approved learning objective to state that energy is conserved in chemical reactions. This exam-check version keeps the answer anchored to Energy transfer during exothermic and endothermic reactions within Exothermic and endothermic reactions, 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 Energy Conservation
Students often think that energy is lost during chemical reactions instead of being conserved.
Emphasize that energy is conserved in chemical reactions; it can change forms but is never lost.
