AAMC FL 3 Flashcards
pOH calculation from pH
pH + pOH = 14
cholesterol stucture
4 fused rings
period
peak to peak or trough to trough
activation energy
transition state energy - reactant energy
thermodynamic stability
can determine from heat of combustion; Thermodynamic stability occurs when a system is in its lowest energy state, or chemical equilibrium with its environment.
aldol condensation
enol form of one aldehyde performs nuc attack on carbonyl of second aldehyde or ketone –> an aldehyde and an alcohol one carbon apart
dehydration –> a double bond btween the middle carbon and former alcohol (alpha, beta unsaturated aldehyde)
porphyrin
5 sided heterocycle with N and DB opposite nitrogen
pH and pI relationship
if pH > pI –> -
if pH < pI –> +
capacitance
capacitance = charge/voltage
Energy stored by Capacitors
U = 1/2QV = 1/2CV^2 = 1/2Q^2/C
proton exchange
occurs between lone pairs on elements and water in aqueous solution; implications for labeling
how to tell if something is a redox reaction
do the oxidation numbers for all the elements involved; if changed, its a redox reaction
amu
one molecule oxygen has is 16 amu
and
one mole of oxygen has a mass of 16 g
property of waves not affected by medium
frequency
resistivity
the inverse of conductivity
