Question
- A. state: correct Unit 4.5 answer for Energy transfer during exothermic and endothermic reactions
- B. Incorrect label: confuses the labelled quantity with activation energy
- C. Incorrect label: places the idea on the wrong part of the reaction or cell model
- D. Incorrect label: uses the product/reactant relationship the wrong way round
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 calculation 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.
