CHEM 0900 Study Guide - Oxoacid, Formula Unit, Molecular Mass
Document Summary
Matter: anything that is occupying space or has a mass. Liquid: definite volume but assumes the shape of container. Gas: no fixed volume or shape, assumes the shape of its container. Physical properties: temperature, pressure, mass, volume, state, melting point, boiling point, density, color, shape of solid crystals, hardness, brittleness, heat capacity. **dependence of the properties on the amount of the sample. Intensive properties: independent of the amount of the sample. Intensive: temperature, state, melting point, boiling point, hardness, density, brittleness, color. Homogeneous mixture: looks completely uniform and consists of two or more substances in the same phase. (solutions) Heterogeneous mixture: is clearly not uniform when seen without magnification. %a= (amount of a/total amounts of a and b)x100% Compound: a pure substance with a constant composition that can be broken down into elements by chemical processes. Element: a pure substance that cannot be decomposed into simpler substances by chemical means. Introduced the concept f the smallest possible particle of matter.
