What is the law of conservation of mass and how does it apply to chemical reactions?

The law of conservation of mass states that mass in an isolated system ans it is neither created or destroyed by chemical reactions or by physical transformations

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.
