c/p fl 3 Flashcards
capacitance
C = Q/V
how can you determine relative thermodynamic stability
-the amount of heat produced
- heats of combustion
ideal gas law
PV = nRT
ideal gas law value for R
8.314 J/mol or 0.0821 L*atm/mol * K
Kb > Ka
Kw/Ka = Kb
If Kb is greater than Ka, then that molecule is considered a base.
energy of activation
the minimum energy barrier necessary to be overcome by the reactants on the path to products.
Ea = activated complex minus the energy of the reactants.
period of a time varying signal
the time between consecutive pulses (shortest repitition time)
Pulse on + pulse off = period of a time varying signal
electric field is uniform between electrodes means that the electric field lines;
are eqally spaced at both electrodes and between them
oxidation agents
NAD+ and FAD
formation of a peptide bond creates what by-product?
water, H2O, 18 amu
Ph for aqueous solutions at 25C
[H3O+] x [OH-] = 10^-14
what coordinates with cations?
Lewis bases (electron donor)
heme
porphyrin, pyrrole ring: five sided heterocycle containing a nitogen atom
resistvity
inverse of conductivity.
cation exchange column
only binds to charged proteins, which only occurs when pH is less than the pI (isoelectric focusing points)
