When iron rusts in the presence of oxygen, iron (III) oxide is produced. How many moles of oxygen react with 9.8 moles of iron in the rusting reaction?

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.
