Match the following statements with their correct interpretation:
Reactions that release energy require energy to get started. = False Energy can be created during a chemical reaction. = False Where does the energy in a chemical reaction come from? = Chemical bonds or surrounding environment How do hot and cold packs become hot or cold so quickly? = Chemicals inside the packs undergo a temperature change
Match the following concepts with their descriptions:
Match the following concepts with their descriptions:
Energy Transfers = All matter is constantly moving, and more energy leads to increased particle movement and collisions. Thermal Energy in Chemical Reactions = Some reactions release thermal energy, while others absorb it due to breaking or forming of chemical bonds. Purpose of Medical Instant Cold or Hot Packs = To induce a temperature change by mixing chemicals inside the pack. Creation of Energy in Chemical Reactions = Energy cannot be created during a chemical reaction.
Match the following with their correct roles in chemical reactions:
Match the following with their correct roles in chemical reactions:
Breaking of Chemical Bonds = Requires energy Releasing of Energy = Occurs in some reactions Absorption of Energy = Occurs in some reactions Initial Energy Requirement for Reactions = Not necessary for reactions that release energy

Study Notes
Matching Concepts and Descriptions
- Match the following: This indicates a task where you need to associate sets of related information.
Identifying Roles in Chemical Reactions
- Understand that chemical reactions involve substances transforming into new ones.
- Identify the roles of various components within these reactions (e.g., reactants, products, catalysts).
Determining Properties
- Focus on the characteristics of substances or materials.
- Properties can relate to physical aspects (e.g., color, density, melting point) or chemical behavior (e.g., reactivity, flammability).
