|
How do you write a rxn involving Ksp?
|
break solid into its ions
|
|
How do you determine which way a rxn will shift?
|
either a) calculate Q or b) use up and down arrows if not given numbers
|
|
How do you determine who will get oxidized or reduced?
|
look at reduction potentials; higher reduction potential, more likely it will be reduced
|
|
What makes an acid a strong base?
|
a) stable conjugate bases w/ resonance structures
b) lots of electronegative atoms pulling on H |
|
How do you know electrolysis is happening?
|
negative voltage, positive delta g, energy being added
|
|
When do you use an integrated rate law?
|
a kinetics question involving time
|
|
What is the half-life expression for a 1st order rxn?
|
t1/2=.693/k
|
|
What makes a metal really reactive?
|
loses electrons really well, low reduction potential, group 1A metal
|
|
What is the % error calculation?
|
(actual-theoretical)/theoretical x100
|
|
What is the equation for osmotic pressure?
|
OP=MRT (R=.08 atm L/n K)
|
|
Who do you calculate molar mass from osmotic pressure?
|
solve for M, use L to get to moles, mass over moles
|
|
Formulas of: a) ethanoic acid b) ethanol c) ethanal d) ethyl amine e)diethyl ether f) propanone
|
a) CH3COOH b) CH3CH2OH c) CH3CHO d) CH3CH2NH2

amine
|
|
Which funtctional groups can form H-bonds?
|
caboxylic acid, amine, alcohol
|
|
What is an isotope?
|
same element, different mass, different number of neutrons
|
|
Whta is the difference between the Bohr and quantum model of the atom?
|
Bohr: electron as particle, can know electron location
Quantum: electron as a wave, cannot know where e- is |
|
How do we know there is a nucleus?
|
Rutherford experiment- shot alpha particles at atom, some were deflecte, indicating a dense positive charge
|
|
Under what conditions do gases dissolve best (and act the least ideal?
|
low temperatures and high pressures
