If 40. 0 g s is allowed to react as completely as possible with 150. 0 g f2(g), what mass of the excess reactant is left?.

30litre of li2o is 1.0002mole approximately 1 mole

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.

A1 a 2 a 3 ooh lol i think that's it
