equations

Question 1

Equilibrium

Answer 1

Kc=[concentration of products]/[concentration of reactants]

Question 2

Acid Dissociation

Answer 2

Ka=[concentration of products]/[concentration of reactants]

Question 3

Base Dissociation

Answer 3

Kb= [concentration of products]/[concentration of reactants]

Question 4

*Water Dissociation

Answer 4

Kw=[H3O(+)][OH(-)]

Question 5

[H3O(+)] to pH

Answer 5

pH=-log[H3O(+)]

Question 6

[OH(-)] to pH

Answer 6

1. use Kw to find [H3O(+)]
2. place it in pH equation

Question 7

Balancing Neutralizing Equations

Answer 7

1. write reactants and products
2. balance H+ in the acid with the OH- in the base
3. balance H2O with the H+ and the OH-
4. write the salt from the remaining ions

Question 8

Buffer Equation

Answer 8

[H3O(+)]= Ka • (weak acid / conjugate base)

Question 9

Specific Heat (no phase change)

Answer 9

q=mSH^T

Question 10

Specific Heat (phase change + heating/cooling)

Answer 10

q total= mSH^T + m^H

Question 11

Combined Gas Law

Answer 11

P1V1/T1 = P2V2/T2

Question 12

Dilution

Answer 12

C1V1 = C2V2

Question 13

osmotic pressure

Answer 13

higher concentration = higher osmotic pressure

Question 14

Kb from Ka

Answer 14

KaKb=Kw

Question 15

rate of reaction

Answer 15

change in concentration of reactant or product / change in time
