front 1 Chemistry | back 1 The study of matter and energy and how they interact. |
front 2 Matter | back 2 anything that has volume, takes up space, and has mass |
front 3 Density | back 3 The ratio of an object’s mass to its volume. It is a measure of how tightly packed the matter is. |
front 4 Colloid | back 4 A heterogeneous mixture with particle that cannot be easily separated |
front 5 Homogeneous mixture | back 5 A mixture that has uniform appearance and properties throughout but can be made of multiple elements mixed together (such as a metal alloy), multiple compounds and elements mixed together (such as air), or multiple compounds mixed together (such as a solution of sugar in water) |
front 6 Heterogeneous mixture | back 6 A mixture that is clearly not uniform throughout and can be made of multiple compounds, multiple elements, or a combination of compounds and elements mixture – a substance that is made by mixing two or more parts, either compounds or elements, that do not chemically combine |
