Chapter 6 Vocabulary
Chapter 6 vocabulary and other 4 terms.
| Term | Definition |
|---|---|
| Reactants | a substance of molecule that participates in a chemical reaction. |
| Products | 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 reactions that requires heat. |
| Synthesis Reaction | a reaction in which substances combine to form a new compound. |
| Decomposition Reactions | a reaction in which a single compound breaks down to form two or more simpler substances |
| Electrolysis | 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. |
| 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 apparent exchange of atoms or ions between two compounds. |
| Oxidation-Reduction Reaction | any chemical change in which one species is oxidized (lose electrons) and another species is reduced (gains electrons) also called redox reaction. |
| Radicals | an organic group that has one or more electrons available for bonding. |
| Chemical Equation | representation of a chemical reaction that uses symbols to show the relationship between the reactants and the products. |
| Mole Ratios | the relative number of moles of the substances required to produce a given amount of product in a chemical reaction. |
| Catalysts | 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 | the reactant in reactions catalyzed by enzymes |
| Chemical Equilibrium | a state of balance in which the rate of a forward reaction equals the rate of the revers reaction and the concentrations of products and reactants remain unchanged. |
| Mole | the SI base unit used to measure the amount of a substance whose number of particles is the same as the number of atoms of carbon in 12 g of carbon -12 |
| Avogadro's Constant | equals 6.02 x 10*23, the number of particles in 1 mol |
| Molar Mass | the mass in grams of 1 mol of a substance |
| Conversion Factor | a ration that is derived from the equality of two different units and that can be used to convert from one unit to the other. |
