Upon heating, calcium carbonate decomposes to calcium oxide and carbon dioxide. (a) Determine the theoretical yield of CO2 if 235.0 g CaCO3 is heated.
(b) What is the percent yield of CO2 if 94.0 g CO2 is collected?

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.
