| Question | Answer |
|---|---|
| Avogadro's Constant | The number of constituent particles in ole mole of a given substance. |
| Mole | A unit of measurement used in chemistry to express amount of a chemical substance. |
| Molar Mass | The mass of a given substance divided by its amount of substance. |
| Conversion Factor | Changes something to a different version or form. |
| Reactant | A substance or molecule that participates in a chemical reaction. |
| Product | A substance that forms in a chemical reaction. |
| Chemical Energy | The energy released when a chemical compound reacts to produce new compounds. |
| Exothermic Reaction | A chemical reaction in which heat is released to the surroundings. |
| Endothermic Reaction | A chemical reaction that requires heat. |
| 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. |
| Electolysis | The process in which an electric current is used to produce a chemical reaction, such as the decomposition of water. |
| Combustion Reaction | The oxidation reaction of an organic compound, in which heat is released. |
| Double-Displacement Reaction | A reaction in which a gas, a solid precipitate, or a molecular compound forms from the apparent exchange of atoms or ions between two compounds. |
| Oxidation-Reduction Reaction | Any chemical change in which one species is oxidized (loses electrons) and another species is reduced (gains electrons); also called redox reaction. |
| Radical | An organic group that has one or more electrons available for bonding. |
| Chemical Equation | A representation of a chemical reaction that uses symbols to show the relationship between the reactants and the products. |
| Mole Ratio | The relative number of moles of the substances required to produce a given amount of product in a chemical reaction. |
| Catalyst | A substance that changes the rate of a chemical reaction without being consumed or changed significantly. |
| Enzymes | A type of protein that speeds up metabolic reactions in plants and animals without being permanently changed or destroyed. |
| Substrate | A part, substance, or element that lies beneath and supports another part, substance, or element; the reactant in reactions catalyzed by enzymes. |
| Chemical Equillibrium | A state of balance in which the rate of a forward reaction equals the rate of the reverse reaction and the concentrations of products and reactants remain unchanged. |
