1) Calculate the empirical formula of a compound with 36g of carbon and 96g of oxygen.

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.

The answers are 3.c kelvin4.b liquids only
