|---|---|
 composition | to classify matter according to its... |
| elements, compound, homogeneous mixture, and heterogeneous mixture | distinguish among: |
| mixture | most matter occurs as a... |
| physical combination | two or more substances; pure elements or compounds |
| chemistry | science that investigates and explains the structure and properties of matter |
| analysis | break down or decompose the components of a chemical compound |
| synthesis | put together or compose a chemical compound |
| matter | anything that takes up space and has mass (all substances are matter, not all matter is a substance) |
| mass | measure of the amount of matter that an object contains |
| properties of matter | characteristics and behavior of matter |
| macroscopic | behavior and observed composition of matter detected with the senses |
| microscopic | used to describe composition and behavior that can only be seen through a microscope |
| submicroscopic | determine how the hidden structure of matter influences its behavior |
| model of the submicroscopic | explain and predict the observed macroscopic behavior |
| scientific models | built on investigation and observation and explain macroscopic observations |
| qualitative | observation made without measurements; descriptions |
| quantitative | observation made with measurements; weights |
| substance | matter with the same fixed composition and properties; pure |
| mixture | combination of 2 or more substances in which the basic identity of each substance is not changed |
| mixture | what can be separated by physical process? |
| physical change | change in matter that doesn't involve a change in identity of the substance |
| boiling, freezing, melting, evaporating, dissolving, and crystallizing | examples of physical changes: |
| heterogeneous mixture | doesn't have a uniform composition and its individual substances remain distinct; pizza |
| homogeneous mixture; solution | uniform composition and is the same throughout |
| solution | consist of a solute that is dissolved into a solvent; solutions are homogeneous mixtures, but not all homogeneous mixtures are solutions |
| alloy | solid solution that contains different metals and sometimes nonmetallic substances |
| solute | substance being dissolved |
| solvent | substance that dissolves the solute |
| aqueous solution | when the solvent is water, the solution is called? |
| compounds and elements | 2 types of pure substances |
| physical property | Those that don't involve changes in composition |
| element | simplest form of matter |
| compound | chemical combination of 2 or more different elements joined together in a fixed proportion |
| formula | combination of the chemical symbols that show what elements make up a compound and the number of atoms of each element |
| chemical change | otherwise known as a chemical reaction |
| chemical property | observed only when there is a change in the composition of the substances |
| analysis & synthesis | 2 primary types of procedures when investigating matter? |
| chemical properties influence physical properties | do chemical properties influence physical properties or do physical properties influence chemical properties? |
| universal solvent | water is a...solvent |
| alloys, aqueous solutions and tinctures | 3 main categories of homogeneous mixtures |
| tinctures | solutions where water isn't the solvent (ink and alcohol) |
| analysis and synthesis | which words are associated with chemical properties? |
| mixture | which word is associated with physical properties? |
