| 746585778 | amalgam | dental fillings, mercury in silver | |
| 746585779 | dilute | little bit of solute and large amount of solvent | |
| 746585780 | endothermic | breaking bonds, the surroundings become cooler | |

| 746585787 | exothermic | forming bonds, the surroundings become warmer | |
| 746585788 | colligative | properties of solutions which depend on concentration rather than the identity of the solute | |
| 746585789 | electrolyte | dissolves in water and conducts electricity | |

| 746585797 | nonelectrolyte | dissolves in water and doesn't conduct electricity | |
| 746585798 | solvent | the substance in greater amount when a solution contains two gases or two liquids | |
| 746585799 | heating, crushing, mixing, stirring | things that can be done to increase the rate of dissolving of a solid in a liquid | |
| 746585800 | activation energy | the energy that is required in a collision to break the bonds in the reactants | |
| 746585801 | collision theory | a reaction requires that reactants collide to form products | |
| 746585802 | equilibrium | the condition in which the rate of the forward reaction is equal to the rate of the reverse reaction | |
| 746585803 | heterogeneous equilibrium | equilibrium components are present in at least two different states | |
| 746585804 | catalyst | a substance that lowers the activation energy and increases the rate of reaction | |
| 746585805 | equilibrium constant expression | the ratio of the concentrations of products reactants with each component raised to an exponent equal to its coefficient | |
| 746585806 | strong electrolyte | a substance that dissolves into ions when it dissolves in water | |
| 746585807 | percent concentration (m/m) | shows only the reactants undergoing a change | |
| 746585808 | weak electrolyte | a solute that forms a few ions but mostly molecules in water | |
| 746585809 | net ionic equation | the maximum amount of a solution that can dissolve under given conditions | |
