Mix And Flow Chapter 2

Question 1

Matter

Answer 1

Matter can be hard, soft, rough, smooth, round, hot or cold. Matter is what makes up the universe

Question 2

Pure substance

Answer 2

Ex. Sugar is made up of only one kind of matter. Can’t be separated into different substances

Question 3

Mixture

Answer 3

Such as soil is made up a combination of different substances sometimes can be separated into different substances

Question 4

Mechanical mixture

Answer 4

You can see the different substances that make up a mixture

Question 5

Heterogenous mixture

Answer 5

You can’t see the different substances that make them up. These mixtures may be solution, suspensions or colloids.

Question 6

Solution

Answer 6

Look as if it’s one substances also known as a homogeneous mixture

Question 7

Homogeneous mixture

Answer 7

Looks as one substance but actually two or more

Question 8

Suspension

Answer 8

Is a cloudy mixture in which droplets or tiny pieces of one substance are held within another substance

Question 9

Colloid

Answer 9

Is also a cloudy mixture but the droplets or tiny pieces are so small that they do not separate easily

Question 10

Solute

Answer 10

The substance that dissolves

Question 11

Solvent

Answer 11

The substance that does the dissolving

Question 12

Concentration

Answer 12

Of a solution tell you the amount of solute dissolved in a specific amount of solvent

Question 13

unstaurated solution

Answer 13

an unstaurated solution is one in which more solute can dissovle

Question 14

saturated solution

Answer 14

a saturated solution is a solution in which no more solute can dissovle at a given temperature

Question 15

solubility

Answer 15

the maximum amount of solute you can add to a fixed volume of solvent at a given temperature

Question 16

satuation point

Answer 16

every solution has a satuation point at a given temperature

Question 17

what three factors solubility depends on?

Answer 17

the type of solute, the type of solvent and the temperature

Question 18

aqueous solution

Answer 18

the solvent is water

Question 19

difference between solvent and solute

Answer 19

the solvent is doing the dissolving and solute is what is being dissolved

Question 20

What is the difference between saturated and unstaurated

Answer 20

an unsaturated solution us one more solute can dissolved and a saturated solution is one that cant dissolved more solute

Question 21

How do you know which has a higher contraction

Answer 21

a solution has 50g of solute dissolved in 100ml of water this read 50g/100ml if something said 75g/10ml you would know that has a higher concentration

Question 22

how much salt is the maxium you can add to water?

Answer 22

35.7g

Question 23

solubity changes with temperature

Answer 23

solubity increases as the temperuture of the solvent increases

Question 24

chromatograms

Answer 24

when ink and water are put on paper the water soaks into the paper and is eventually dissolve the ink spots.. The distance the substance moves depends on its attraction to the paper. Those with the strongest atterenction to paper dont move very far. those with the weakest move farther
