MNEMONICS
MCAT Chemistry/Physics
GENERAL CHEMISTRY
Molar mass (MM) of a gas is what a dog does outdoors.
"Dirt Over Pee" "Dirt over pee" or MM=dRT/P
(D=density, R=ideal gas constant, T=temp, P=pressure)
Oxidation & Reduction
"LEO the lion, goes GER" LEO the lion, goes GER
Loss of Electrons ⇒Oxidation
Gain of Electrons ⇒Reduction
Types of White Blood Cells
Never Let Monkeys Eat Bananas (from most abundant to least abundant)
"Never Let Monkeys Eat Bananas" Neutrophils
Lymphocytes

Eosinophils
Basophils
Change in Gibbs Free Energy Under Non-standard Conditions
"Delicious Grapefruit - Not For Everyone"
DG° = -nFE°
Nernst Equation:
"We minus Arty (is) enough, thank you."
E = E° - (RT/nF)lnQ
Chemical Bonds
H requires 1 more electron in its outer shell to become stable.
HONC O requires 2.
N requires 3.
C requires 4.
Reduction occurs at the Cathode; Oxidation at the Anode.
Cathode/Anode Memory Trick
Remember that the terms beginning with consonants (R & C) are together,
and those beginning with vowels (O & A) are together.
Gibb's Free Energy
"Good Honey Tastes Sweet"
DG = DH - TDS
"HK + AHA" Henderson-Hasselbalch Equation
Hong Kong + American Hospital Association pH = pKa + log10(A-/HA)
Quantum Numbers:

n, l, m, s
State Functions
V for volume
G for Gibb's free energy
"VG PHEST" (Very Good Festival) P for pressure
H for enthalpy
E for internal energy S for entropy
T for temperature
Cation:
"CA+ION." The "t" in cation looks like a plus sign: "ca+ion"
This is a reminder that cations are positively charged.
"MIT enough" Moles deposited at an electrode = It/nF
Thermodynamics: Gibbs Free Energy
"Gee! Plus Arty! Thank you!"
ΔG = ΔG°+ RTlnQ
