| Synthesis Reaction | A reaction in which two or more substances combine to form a compound. |
| Decomposition Reaction | A reaction in which a single compound breaks down to form two or more simpler substances |
| Combustion Reaction | Always involves an organic compound that reacts with oxygen; it produces carbon dioxide and water. |
| Single Displacement Reaction | A reaction in which one element takes the place of another element in a compound. |
| Precipitate | A solid that is formed from a chemical solution. This often occurs with double displacement reactions. |
| Aqueous | Used to indicate when a chemical is dissolved in water. |
| Law of Conservation of Mass | States that matter in a chemical reaction can neither be created nor destroyed. This law is the reason why chemical equations need to be balanced. |
| Law of Conservation of Energy | States that energy in a chemical reaction can neither be created nor destroyed |
| Coefficient | A number placed in front of a product or reactant that tells the number of atoms reacting in an equation (by multiplication). |
| Produce/Yield | Indicated by the ----> arrow in a chemical reaction. Indicates what will come out of a chemical reaction. |
| Solubility | The ability of one substance to dissolve in another at a given temperature and pressure. |
| Reactant | A chemical or molecule that participates in a chemical reaction. It is located on the left side of a chemical equation. |
| Product | A chemical or molecule that is formed in a chemical reaction. Located on the right side of a chemical equation. |
| Chemical Equation | This represents a chemical reaction and shows the relationship between reactants and products |
| Balanced Chemical Equation | A representation of a chemical reaction that correctly accounts for each atom that reacts and each atom that is produced. It follows the law of conservation of mass. |
| Chemical Energy | Energy that is stored in the form of chemical bonds |
| Endothermic Reaction | A type of reaction where energy is absorbed, such as an instant ice pack. More energy is needed to break the bonds of the reactants than is given off by forming the bonds of the products. |
| Exothermic Reaction | A type of reaction in which energy is released, such as the combustion of a car engine. |
