| Question | Answer |
| salt | formed from acid-base reaction, aqueous solution that turns solid when water is evaporated |
| mass percent | mass of element in mole of compound of weight of mole of compound |
| empirical formula | formula of a compound that expresses the smallest whole number ratio of the atoms present |
| molar mass | the mass (in grams) of 1 mole of the substance |
| Avogadro's number | 6.02*10^23 (1 mole of something consists of 6.02*10^23 units of that substance) |
| average atomic mass | way for elements to be composed of identical carbon atoms |
| atomic mass unit (amu) | unit of mass |
| decomposition reaction | start with compound (AB=A+B) (type of oxidation-reduction reaction) |
| synthesis reaction | start with elements (A+B=AB) (type of oxidation-reduction reaction) |
| combustion reaction | chemical reactions that involve oxygen and produce energy (heat) so rapidly that a flame results (type of oxidation-reduction reaction) |
| acid-base reactions | involves an H+ ion that ends up in the product water |
| double-displacement reaction | double exchange (AB+CD=AD+CB) |
| oxidation-reduction reaction | a reaction that involves a transfer of electrons |
| strong bases | strong electrolytes that contain OH- ions |
| base | a substance that produces hydroxide ions (OH-) in water ( |
| strong acids | strong electrolytes that produce H+ ions |
| acid | substance that produces H+ ions (protons) when it is dissolved in water |
| net ionic equation | includes only those directly involved in the reaction |
| spectator ions | ions that do not participate directly in a reaction in solution |
| complete ionic equation | all substances that are strong electrolytes are represented as ions |
| molecular equation | shows the complete formulas of all reactants and products |
| slightly soluble solid | a solid where such a tiny amount dissolves in water that it is undetectable with the naked eye |
| insoluble solid | a solid where such a tiny amount dissolves in water that it is undetectable with the naked eye |
| soluble solid | solid that readily dissolves in water |
| strong electrolyte | a material that when dissolved in water conducts electricity, (by ions) |
| precipitation reaction | reaction of two solutions to form a solid |
| precipitate | solid that forms |
| precipitation | process of a formation of a solid |
