Topic 2-Mix & Flow

Question 1

Pure Substance

Answer 1

A substance made up of only one type of matter.

Question 2

Mechanical Mixture

Answer 2

Heterogeneous mixture. A mixture in which the different substances are easy to see.

Question 3

Mixture

Answer 3

Combination of two or more different pure substances.

Question 4

Soloution

Answer 4

Homogeneous mixture

Mixture of two or more pure substances that looks like one substance.

Question 5

Heterogeneous Mixture

Answer 5

Mixture in which the different substances can be seen.

Question 6

Homogeneous Mixture

Answer 6

A mixture in which the different substances cannot be seen

Question 7

Suspension

Answer 7

Cloudy mixture in which droplets or tiny pieces of one substance are held within another substance. If you leave a suspension undisturbed, its parts will usually separate out.

Question 8

Colloid

Answer 8

Cloudy mixture in which the droplets or tiny particles are too small to separate out.

Question 9

What are some examples of mechanical mixtures? (Heterogenous)

Answer 9

Trail Mix
Chicken Noodle Soup
Cereal

Question 10

What are some examples of solutions? (Homogeneous)

Answer 10

Cake Batter
Lemonade
Jello
Salt Water

Question 11

What are some examples of suspensions?

Answer 11

Orange juice with pulp

Muddy water

Question 12

What are some examples of colloids?

Answer 12

Milk
Whipped Cream
Butter

Question 13

What is paper chromatography?

Answer 13

It is a test of fluids to see if they are pure substances or solutions. I’m he test a piece of filter paper is placed partially into the fluid. If the fluid is a solution, the different substances in it will move up the paper to different levels. If it is a pure substance it will move up the paper to one level

Question 14

What is a chromatogram?

Answer 14

It’s the filter paper used to test substances used in paper chromatography.

Question 15

Solute

Answer 15

Substance that dissolves in a solvent to form a solution.

Question 16

Solvent

Answer 16

Substance that dissolves a solute to form a solution.

Question 17

What are some popular solvents?

Answer 17

Water and alcohol

Question 18

Concentration

Answer 18

The amount of solute dissolved in a specific amount of solvent in a solution.

Question 19

What measurement is the concentration of a solution written in?

Answer 19

g/mL

kg/L

Question 20

Unsaturated Solution

Answer 20

Solution in which solvent will dissolve. If there is too much solvent then the solution becomes saturated.

Question 21

Saturated Solution

Answer 21

Solution in which no more solute can be dissolved because there is already to much in it.

Question 22

Saturation point

Answer 22

A point at which no more solute can be dissolved in a given volume of solvent.

Question 23

Solubility

Answer 23

The maximum amount of solute you can add to a fixed amount of solvent.

Question 24

Aqueous Solution

Answer 24

A solution in which the solvent is water.

Question 25

What are the four main points in the particle model of matter?

Answer 25

1. ) All matter is made up of tiny particles. Different substances are made up of different particles.
2. ) The tiny particles of matter are always moving and vibrating
3. ) the particles in matter may be attracted to each other or bonded together.
4. ) the particles have spaces between them.

Question 26

What three factors help solutes dissolve quicker

Answer 26

Temperature
Size of Pieces
Stirring

Question 27

What is the process of dissolving?

Answer 27

In a solution, the particles of the solute are attracted to the particles of the solvent. The solute dissolves in the solvent.
