BP FL3 Flashcards
The quantity T∆S, not ∆S, must be greater than ∆H
to make G spontaneous and H positive !!!
Entropy and G and H depend on
TEMPERATURE to make G spon or nonspon
if high temp and H positive, S is positive at high T
azimuthal quantum number of l = 0
s and l=1 is p
The two valence electrons for ground state beryllium are in an orbital with an azimuthal quantum number of l = 0,
whereas the third valence electron in ground state boron must be in an orbital with an azimuthal quantum number of l = 1.
So right side has p and left side has s and middle has d
why 2p is easier to ionize than 2s?
p is further away from the nucleus so it is easier to ionize !!!
When an electron drops energy levels (emission)
it releases energy as a photon (ejects)
Mass number is
proton + neutron
Atomic mass = proton +neutron of the mass of that atom
Atomic weight is the avg of the isotopes
Free radicals from ionizing radiation are highly unstable and have carcinogenic effects. These effects are most likely result from damage to:
nucleic acids (DNA)
cancer cells disrupt the DNA replication !
sp has the lowest energy so
highest nm (wavelength)
vf2= vi2 +2ad
Vf= Vi+at
d= vt +1/2at2
alpha particle has
2p and 2 n so 4 mass number
beta decay or particle has
same mass as an electron so 1/1800 of a proton
The proton mass is 1800 higher than
electron
A cell’s ATP-to-ADP ratio is most nearly equal to the ratio of its fluorescence emission intensities when Y32 is excited at:
when the peak are similar
HI and HBr are
HClO4 (perchloric acid)
strong acids
Weak acids have large pKa’s (2 — 50);
acetic acid is waek acid
When working with complex acid structures
do H and HA and A- rather than writing the complex rxn to calculate
Ka= H A/ HA
To calculate percent yield
measure the moles of each reactant and look at the excess and with that measure the product
Percent yield
actual/theoretical x100
CALCULATE THE EXCESS
P Q R on heart beat involves
depolarization !!!
repolarization is downwards
