What fundamental law is demonstrated in balancing equations?

Balancing equations demonstrates the fundamental law of the conservation of mass. It shows that you cannot create or destroy mass in a chemical reaction, so the mass stays constant.

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.
