Calculate the sodium ion concentration when 64.0 mL of 5.0 M sodium carbonate is added to 22.0 mL of 1.2 M sodium bicarbonate.

Ibelieve its a because an empirical formula usually has a ch in it your options are a or b

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.

What do you mean by that? like the contents? the thc level?
