Extensive properties |
amount of matters (volume, mass, length); quantitative |
|
Intensive Properties |
type of matter; amount doesn't matter (density, color, elasticity); qualitative or quantitative |
|
Physical Change |
change extensive, but not intensive properties; properties change but composition doen't |
|
Chemical Change |
intensive properties change; different composition |
|
Solid |
definite shape and volume (tightly packed) |
|
Liquid |
has indefinite shape, flows, but has a fixed volume (slide past eachother) |
|
Gas |
matter takes shape and volume of its container (bump into eachother) |
|
Mixtures |
physical blend of 2+ components |
|
Heterogeneous Mixture |
Composition is not uniform through and through (ex: hamburger- you can see meat, bun, and cheese) |
|
Homogeneous Mixture |
Composition is uniform throughout (ex: olive oil mixed with vinegar); solution |
|
Filtration |
process that separates a solid from the liquid in a heterogeneous mixture |
|
Distllation |
when a liquid is boiled to produce a vapor that is then condensed into a liquid; separation by boiling point |
|
Element |
simplest form of matter with a unique set of properties |
|
Compound |
Substance containing 2+ elements chemically combined in a fixed proportion (ex: O, C, and H are fixed in a compound called sucrose) |
|
Chemical Change |
produces matter with different composition than the original matter |
|
Chemical Symbol |
One or two letters; first letter capital; second letter is lowercase; developed by Berzelius (ex: Na, K, Sb, Cu, Au, Ag, Pb, Fe, Sn, etc... |
|
Periodic Table |
arrangement of elements where they are separated into groups based on a set of repeating properties |
|
Period |
Horizontal row on P.T. |
|
Group |
Vertical column of P.T. |
|
Chemical Property |
ability of a substance to undergo a chemical change; what would happen |
|
Chemical Reaction |
1+ substances changing into 1+ new substances |
|
Reactant |
substance present at the start of a reaction |
|
product |
substance produced in a reaction |
|
Precipitate |
a solid that forms and settles out of a liquid mixture |
|
Clues a chemical change has taken place |
1. Bubbles 2. Color Change 3. Heat 4. Precipitate
|
|
Conservation of Mass |
In any physical change or chemical reaction, mass is conserved; mass is not created or destroyed |
