| chemical property | substance that describes its ability to change into another substance |
| chemical change | chance in one substance into a brand new substance |
| physical property | substance that can be observed without changing the substances inito another substance |
| physical change | a substance under goes changes in size shape or state of matter |
| law of conservation of Mass | Matter is neither created nor destroyed during a chemical change |
| element | Pure substances are made up of only one type of atom |
| atom | smallest part of an element |
| compound | atoms of two or more elements that are chemically combined into a specific ratio |
| substance | is either an element of compound |
| chemical Reaction | process that occurs when a substance undergoes a change and a new substance is created |
| chemical equation | shows the change that takes place during a chemical reaction |
| coefficient | number of units of substance involved in a chemical reaction |
| mixture | two or more substances that are physically combined |
| Heterogeneous Mixture | one in which different types of materials can be identified |
| precipitate | solid forms in a solution during a chemical reaction |
| colloid | this contains tiny undisclosed particles that are evenly mixed but NEVER separated |
| suspension | a mixture in which particles can be seen and are easily separated by settling or filtering |
| homogeneous Mixture | Two or more substances that are evenly mixed and you can not see the different particles |
| solvent | substance which dissolves the solute |
| electrolyte | chemical compound that can produce an electrical current/conducts electricity |
| solubility | tells us how well a solute can be dissolved into a given amount of solvent |
| solubility Graph | used to summarize the solubiliy of several substances at a given mass(grams) of water as temperatures (c) increase |
| unsaturated solutions | solutions that can hold more solute at a given temperature |
| saturated solution | a solution that holds the maximum amount of solute for a given temperature |
| supersaturated solution | a solution that holds more solute than it normally would for a given temperature |
