Question 1

Solute

Answer 1

Substance being dissolved

Question 2

Solvent

Answer 2

Substance doing the dissolving

Question 3

Solution

Answer 3

Mix of solute and solvent

Question 4

Property of good solvent

Answer 4

Like dissolves like

Question 5

Intramolecular bonds

Answer 5

Within the molecules

Question 6

Intermolecular bond

Answer 6

Between the molecule

Question 7

Hydrogen bonds

Answer 7

Attraction of hydrogen from one polar molecule to a highly electronegative atom of another polar molecule

Question 8

Van der Waals attraction

Answer 8

Intermolecular attraction

Question 9

Types of Van der Waals reactions

Answer 9

Dipole: attraction between polar molecule (hydrogen bonds)

Dispersion/London force: when you have a dipole moment (temporary polar)

Question 10

Unsaturated solution

Answer 10

Solution is capable of dissolving more solute

Question 11

Saturation solution

Answer 11

Solution is holding as much solute as able to be dissolved

Question 12

Super saturated solution

Answer 12

Solution is containing more solute than maximumly possible

Question 13

Enzymes

Answer 13

Protein that lowers the activation energy making a biochemical reactions go faster

Question 14

Activation energy

Answer 14

Energy required to make a reaction start

Question 15

Catalytic strategies

Answer 15

• acid/base
• covalent
• electrostatic
• proximity & orientation

Question 16

Transition state

Answer 16

Highest energy point from start to end (very unstable)

Question 17

Free E of activation

Answer 17

Determines how quickly reaction will go

Question 18

Standard free energy change

Answer 18

Net change

Question 19

What happens when reaction is catalyzed?

Answer 19

Transition state has a much lower energy, becomes more stable with the enzyme, and has a much lower activation energy

Question 20

Actions that can occur by enzymes

Answer 20

Can break apart, build, add, or rearrange molecules

Question 21

Hardness

Answer 21

Ionic=harder, covalent = less hard

Question 22

Conductivity

Answer 22

Ionic=more

Covalent=less

Question 23

Melting point

Answer 23

Ionic=slower

Covalent=faster

Question 24

Capillary action

Answer 24

Polar=more

Non=less

Question 25

Surface tension

Answer 25

Polar=strong

Non=weak

Question 26

Solvent ability for ionic

Answer 26

Polar=dissolves

Non=doesn’t

Question 27

Solvent ability for covalent

Answer 27

Polar=dissolves

Non=does not
