Topic 1: Vocabulary

Question 1

Homogenous Mixture

Answer 1

Uniform composition: the same proportions of its components throughout a given sample.

Question 2

Heterogenous Mixture

Answer 2

Un-uniform composition: proportions of its components are different throughout a given sample.

Question 3

Distillation

Answer 3

The process of purifying a mixture through 2 substances having different boiling points. Boiling the one with the lower boiling point and condensing boiled off substance in a flask.

Question 4

Recrystallization

Answer 4

dissolving impure substance and then recrystallizing it (making sure that everything is enclosed), then filtering the impurities out.

Question 5

Filtration

Answer 5

Using filter to dissolve solid from a solution

Question 6

Solvation

Answer 6

2 solids (1 soluble the other isnt soluble). Dissolving soluble one in water and then filtering out the unsoluble.

Question 7

Evaporation

Answer 7

Evaporating liquid. (pretty straight forward, ain’t it?)

Question 8

Paper chromatography.

Answer 8

Based on the affinity (towards the solution and whether it had a mobility or stationary affinity) will dedictate how far the ink(eg) would move up a paper. Mobil affinity to solution will lead it further down the paper (follows the solution till the tip to where the paper absorbs the solution) & vice versa.

Question 9

Desposition/ desublimation

Answer 9

Transformation from Gas to solid without intersect with the liquid stage.

Question 10

sublimation

Answer 10

Transformation from Solid to gas without intersect with the liquid stage.

Question 11

Melt

Answer 11

from Solid to Liquid

Question 12

Freeze

Answer 12

Liquid to Solid

Question 13

Boil

Answer 13

Liquid to Gas

Question 14

condensation

Answer 14

Gas to Liquid

Question 15

aqueous solution

Answer 15

a solution in which the solvent is water

Question 16

Kelvin

Answer 16

Measurement of Temperature: Proportional to the average Kinetic energy of the particles. Absolute zero is equivalent to NO kinetic energy in the particles. This is approximately -273°C

Question 17

Kelvin –> °C

Answer 17

Kelvin - 273

Question 18

°C—> Kelvin

Answer 18

C° + 273

Question 19

Pure Substance

Answer 19

Element & Compound: chemically bonded

Question 20

Mixture

Answer 20

A mixture is a physical blend of two or more substances that preserve their identities. EG. Heterogenous or Homogenous

Question 21

Answer 21

Mr. HOFBrINCl ( Hydrogen, oxygen, Fluorine, Bromine, Iodine, Nitrogen, Chlorine.)

Question 22

Emission line spectra

Question 23

Electromagnetic spectrum

Question 24

PHOTONSSSS
