Calcium has a resonant transition at 422.7 nm the excited state has a lifetime of 4.5 ns, due only to fluorescence to the ground state. ignore possible degeneracies in the energy levels calculate:
the excited state energy in joules and in ev
the einstein coefficient for spontaneous emission, a
the einstein coefficient for absorption, b
the oscillator strength the maximum extinction coefficient.
the maximum absorption cross section
the transition dipole moment

b) returns freshwater to the earth.

c) returns freshwater to the earth.c) occurs after condensation.

d) returns freshwater to the earth.c) occurs after condensation.d) roughly equal to the amount of evaporation.

happy to

pls mark as brainliest.

i think they are all correct

explanation:

they seem good

im guessing the west of station b

part 1: which substance has a higher solubility?

a

smallest amount left undissolved atall temps in table shown most has dissolved high sol'by
