In a chemical reaction, several aspects can change, including:
1. **Chemical Composition**: The substances involved in the reaction (reactants) are transformed into different substances (products) with distinct chemical compositions.
2. **Chemical Bonds**: The breaking of bonds in the reactants and the formation of new bonds in the products occur during the reaction.
3. **Energy Changes**: Reactions often involve changes in energy, which can manifest as heat release (exothermic reactions) or heat absorption (endothermic reactions).
4. **Physical Properties**: Changes in color, temperature, state (solid, liquid, gas), and odor may occur as a result of a chemical reaction.
5. **Concentration of Reactants and Products**: The amounts of reactants decrease while the amounts of products increase over the course of the reaction.
6. **Equilibrium Position**: In reversible reactions, the balance between reactants and products can shift based on changes in conditions like concentration, temperature, or pressure.
Overall, the essence of a chemical reaction is the transformation of substances, reflected in changes to their chemical identity and physical properties.
