| Term | Definition |
|---|---|
| Chemical Reaction | The process by which one or more substances change to produce one or more different substances. |
| Precipitate | A solid that is produced as a result of a Chemical Reaction in solution. |
| Chemical Formula | A combination of Chemical symbols and numbers to represent a substance. |
| Chemical Equation | A representation of a chemical reaction that uses symbols to show the relationship between the reactants and the products. |
| Reactant | A substance or molecule that participates in a Chemical Reaction. |
| Product | The substance that forms in a Chemical Reaction. |
| Law of Conservation of mass | The law that states that mass cannot be created or destroyed in ordinary chemical and physical changes. |
| Synthesis reaction | A reaction in which two or more substances combine to form a new compound. |
| Decomposition reaction | A reaction in which a single compound breaks down to form two or more simpler substances. |
| Single-displacement reaction | A reaction in which one element or radical takes the place of another element or radical in a compound. |
| Double-displacement reaction | A reaction in which a gas, a solid, precipitate, or a molecular compound forms from the exchange of ions between two compounds. |
| Exothermic reaction | A chemical reaction in which heat is released to the surroundings. |
| Endothermic reaction | A chemical reaction that requires heat. |
| Law of conservation of energy | The law that states that energy cannot be created or destroyed but can be changed from one form to another. |
| Activation energy | The minimum amount of energy required to start a chemical reaction. |
| Inhibitor | A substance that slows down or stops a chemical reaction. |
| Catalyst | A substance that changes the rate of a chemical reaction without being used up or changed very much. |
