Drag each label to the correct location on the image. Each label can be used more than once.
Identify the parts of the energy diagrams.
Labels:

Diagrams:
Chemical Reactions That Absorb Energy – This diagram represents an endothermic reaction where energy is absorbed.
Chemical Reactions That Release Energy – This diagram represents an exothermic reaction where energy is released.
The Correct Answer and Explanation is :
It seems I cannot view the image directly. However, I can guide you through identifying the parts of an energy diagram.
Endothermic Reaction (Energy Absorbed):
- Reactants: The starting materials on the left side of the graph.
- Products: The final substances on the right side.
- Energy Absorbed: The energy is required for the reaction to occur, shown by the upward curve.
- Energy Released: Not applicable in an endothermic reaction, as energy is absorbed.
Exothermic Reaction (Energy Released):
- Reactants: The starting materials on the left side.
- Products: The final substances on the right side.
- Energy Released: This is the energy given off by the system, shown by the downward curve after the reaction.
- Energy Absorbed: Not a key feature here, as the reaction releases energy instead of absorbing it.
In both cases, energy is either absorbed (endothermic) or released (exothermic), reflecting the direction of the chemical change. For endothermic reactions, reactants require more energy to break bonds, and the energy input is higher than the energy released. In exothermic reactions, energy is released when bonds are formed, and the products have less energy than the reactants.
