Question 6

extensive properties

Answer 6

a property that depends on the amount of matter in a sample (mass, volume)

Question 7

intensive properties

Answer 7

a property that depends on the type of matter in a sample, not the amount of matter (color, texture, brittle, density)

Question 8

physical properties

Answer 8

a quality or condition of a substance that can be observed or measured without changing the substance’s composition (color, smell, temperature, shape, density, malleability, state/phase)

Question 9

chemical properties

Question 10

three states of matter

Answer 10

solid, liquid, and gas

Question 11

mixtures

Answer 11

two or more substances combined so that each substance retains its chemical identity

Question 12

what are the two types of mixtures?

Answer 12

heterogenous, homogenous,

Question 13

heterogenous mixtures

Answer 13

a mixture that is not uniform in composition, its components are easily distinguished

Question 14

homogenous mixture

Answer 14

a mixture that is completely uniform in composition, its components are not easily distinguished. called a solution

Question 15

what’s the difference between mixtures and pure substances?

Answer 15

mixtures can be separated while pure substances cannot

Question 16

pure substances

Answer 16

has constant composition and distinct chemical properties (metal, nonmetal, and metalloid elements)

Question 17

methods of separation

Answer 17

distillation, filtration, chromatography, evaporation,

Question 18

distillation

Answer 18

purification process where liquid is evaporated and condensed again to a liquid

Question 19

filtration

Answer 19

(strainer) separating liquids from soldis

Question 20

chromatography

Answer 20

general name for a series of methods for separating mixtures by using a system with a mobile phase and a stationary phase

Question 21

evaporation

Answer 21

vaporization that occurs at the surface of a liquid that is not boiling

Question 22

sublimation

Answer 22

occurs when a solid changes directly to a gas (ice in freeze, carbon dioxide as dry ice)

Question 23

element

Answer 23

a substance whose atoms are all chemically the same, containing a definite number of protons. the simplest form of matter with a unique set of properties. cant be broken down

Question 24

compound

Answer 24

a pure substance that contains more than one element. can be broken down into a more simpler phase

Question 25

properties of compounds

Answer 25

chemical changes and pure substances
