Chemical, matter that has a definite and uniform composition

Front 3

Mass

Back 3

Measurement that reflects the amount of matter

Front 4

Weight

Back 4

The measurement of the amount of mass and the effect of earth's gravitational pull on it

Biochhemistry

Back 5

The study of matter and processes of living organisms (ex. metabolism)

Front 6

Organic chemistry

Back 6

The study of carbon containing chemicals

Physical chemistry

Back 9

The study of the behavior and changes of matter and the related energy changes (ex. Reaction rates)

Front 10

Matter

Back 10

Anything that has mass and takes up space

Front 11

Qualitative data

Back 11

Describes color, odor, shape, or other physical characteristics

Front 12

Quantitative data

Back 12

How much, how little, how big, how tall, or how fast

Front 13

Pure research

Back 13

For the sake of knowledge

Front 14

Applied research

Back 14

Undertaken to solve a specific problem

Front 15

Bar graph

Back 15

Show how a quantity varies across categories (time, location, temperature)

Front 16

Circle graph/pie chart

Back 16

Showing parts of a whole (percentages)

Front 17

Interpolation

Back 17

Can read I between the data points on any point on the line

Front 18

Extrapolation

Back 18

Extending a line beyond the plotted points to estimate values

Front 19

States of matter

Back 19

Solid, liquid, gas

Front 20

Solid

Back 20

Has a definite shape and volume

Front 21

Liquid

Back 21

Flows, constant volume, takes the shape of its container

Front 22

Gas

Back 22

Flows to conform to the shape of its container and fills the entire volume of the container

Front 23

Extensive property

Back 23

Dependent on the amount of substance present (ex. Mass, length, volume)

Front 24

Intensive property

Back 24

Independent of the amount of substance present (ex. Density)

Front 25

Physical property

Back 25

Characteristic that can be observed or measures without changing the subject's composition (ex. Density, color, odor, hardness, melting point, boiling point)

Front 26

Chemical property

Back 26

The ability of a substance to combine with or change into one or more substances (ex. iron forming into rust)

Front 27

Physical change

Back 27

Alters a substance without changing its composition (ex. Cutting paper, breaking glass)

Front 28

Phase change

Back 28

A transition of matter from one state to another

Front 29

Chemical change

Back 29

A process that involves one or more substances changing into a new substance (ex. Rust)
1. Heat and light
2. Different color
3. Precipitate
4. Fizzling/bubbling

Front 30

Law of conservation of mass

Back 30

Mass is neither created or destroyed during a chemical reaction- it is conserved

Front 31

Heterogeneous mixture

Back 31

Does not blend smoothly throughout and individual substances remain distinct (ex. Salad dressing, lucky charms)

Front 32

Homogeneous mixture

Back 32

Has a constant composition throughout (ex. Water)
Also referred to as a solution

Front 33

Element

Back 33

Pure substance that cannot be broken down

Front 34

Compound

Back 34

Made up if two or more elements that are combined chemically (ex. NaCl is salt, sodium and chlorine = sodium chloride)

Front 35

Product

Back 35

End result of a chemical reaction

Front 36

Reactants

Back 36

Two or more substances that react to each other to create products

Front 37

Filtration

Back 37

A technique that uses a porous barrier to separate a solid from a liquid

Front 38

Distillation

Back 38

A separation technique based on differences in the boiling points of the substances involved

Front 39

Crystallization

Back 39

A separation technique that results in the formation of pure solid particles of a substance

Front 40

Sublimation

Back 40

A process in which a solid changes to a vapor

Front 41

Chromotography

Back 41

Separates the components of a mixture (Mobil phase) based on the ability of each component to travel across the surface of another material (stationary phase)

Front 42

Look over lab equipment
