Normal rain has a ph of about 5.5 whereas the most acidic rain measured in los angeles had a ph of 1.5. how much more concentrated in h+ is the acid rain than the normal rain?

PH is used to measure the acidity of a substance and it can be used to calculate the amount of H+ ions in a solution. pH is expressed as:

pH = -log [H+]
For a normal rain:
5.5 = -log [H+]
[H+] = 1 x 10^-5 M

For an acid rain:
1.5 = -log [H+]
[H+] = 0.03 M

There is one s orbital, and there are three p orbitals, five d orbitals, and seven f orbitals. thus, the answer is b. do not confuse the number of orbitals in a subshell with the number of electrons the subshell can hold. each orbital can hold two electrons, so the capacity of an nf subshell is 14 electrons.
