| 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 number to represent a substance |
| Chemical Equation | A representation of a chemical reaction that uses symbol to show the relationship between the reactants and the products |
| Reactant | A substance or molecule that participate 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 to 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 |
