Honors Chemistry Chapter 2- Vocab

Front 1

Extensive properties

Back 1

amount of matters (volume, mass, length); quantitative

Front 2

Intensive Properties

Back 2

type of matter; amount doesn't matter (density, color, elasticity); qualitative or quantitative

Front 3

Physical Change

Back 3

change extensive, but not intensive properties; properties change but composition doen't

Front 4

Chemical Change

Back 4

intensive properties change; different composition

Front 5

Solid

Back 5

definite shape and volume (tightly packed)

Front 6

Liquid

Back 6

has indefinite shape, flows, but has a fixed volume (slide past eachother)

Front 7

Gas

Back 7

matter takes shape and volume of its container (bump into eachother)

Front 8

Mixtures

Back 8

physical blend of 2+ components

Front 9

Heterogeneous Mixture

Back 9

Composition is not uniform through and through (ex: hamburger- you can see meat, bun, and cheese)

Front 10

Homogeneous Mixture

Back 10

Composition is uniform throughout (ex: olive oil mixed with vinegar); solution

Front 11

Filtration

Back 11

process that separates a solid from the liquid in a heterogeneous mixture

Front 12

Distllation

Back 12

when a liquid is boiled to produce a vapor that is then condensed into a liquid; separation by boiling point

Front 13

Element

Back 13

simplest form of matter with a unique set of properties

Front 14

Compound

Back 14

Substance containing 2+ elements chemically combined in a fixed proportion (ex: O, C, and H are fixed in a compound called sucrose)

Front 15

Chemical Change

Back 15

produces matter with different composition than the original matter

Front 16

Chemical Symbol

Back 16

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...

Front 17

Periodic Table

Back 17

arrangement of elements where they are separated into groups based on a set of repeating properties

Front 18

Period

Back 18

Horizontal row on P.T.

Front 19

Group

Back 19

Vertical column of P.T.

Front 20

Chemical Property

Back 20

ability of a substance to undergo a chemical change; what would happen

Front 21

Chemical Reaction

Back 21

1+ substances changing into 1+ new substances

Front 22

Reactant

Back 22

substance present at the start of a reaction

Front 23

product

Back 23

substance produced in a reaction

Front 24

Precipitate

Back 24

a solid that forms and settles out of a liquid mixture

Front 25

Clues a chemical change has taken place

Back 25

1. Bubbles

2. Color Change

3. Heat

4. Precipitate

Front 26

Conservation of Mass

Back 26

In any physical change or chemical reaction, mass is conserved; mass is not created or destroyed
