different, heterogenous

Question 13

what can suspensions do?

Answer 13

suspensions can separate, filter, and scatter light

Question 14

what are electrolytes?

Answer 14

solid that’s dissolved into liquid and produces a solution that conducts electric current

Question 15

example of electrolyte

Answer 15

salt like in gatorade

Question 16

what are nonelectrolytes?

Answer 16

a solution that doesn’t conduct electric current

Question 17

ways to dissolve

Answer 17

crushing the solute
stirring
heating the solvent

Question 18

what is solute?

Answer 18

what gets dissolved

Question 19

what is solvent?

Answer 19

what does the dissolving

Question 20

what is solution equilibrium?

Answer 20

dissolution and crystallization occur at the same rate

Question 21

what is saturated?

Answer 21

the maximum amount of solute

Question 22

what is unsaturated?

Answer 22

less than the maximum amount of solute

Question 23

what is supersaturated?

Answer 23

more than the maximum amount of solute

Question 24

what is solubility?

Answer 24

amount of solute needed to make a saturated solution

Question 25

like dissolves like

Answer 25

polar dissolves polar nonpolar dissolves nonpolar polar dissolves ionic

Question 26

what is immiscible?

Answer 26

2 liquids that don't mix

Question 27

henry's law

Answer 27

dissolving gas into liquid, you add pressure using the same gas

Question 28

example of henry's law

Answer 28

carbonation in soda

Question 29

effects of temperature on solubility

Answer 29

temperature helps solid dissolve into liquid but doesn't help gas dissolve to liquid

Question 30

what is solvated?

Answer 30

when solute is surrounded by solvent

Question 31

what is enthalpy of solution?

Answer 31

energy released or absorbed when solution is made

Question 32

step 1 of energy changes

Answer 32

energy absorbed | solute particles are removed from solids

Question 33

step 2 of energy changes

Answer 33

energy absorbed | solvent molecules get moved from solid

Question 34

step 3 of energy changes

Answer 34

energy released | solvent surrounds solute

Question 35

what is concentration?

Answer 35

amount of solute in a given amount of solution

Question 36

what is molarity?

Answer 36

moles of solute / liters of solute

Question 37

M =

Answer 37

mol / L

Question 38

mol =

Answer 38

ML

Question 39

L =

Answer 39

mol / M

Question 40

what is molality?

Answer 40

moles of solute / kg of solvent
