Which of the following reactions is NOT properly classified? (A) Synthesis - MgO + CO2 → MgCO3
(8) Decomposition - 2 Fe(OH)3 → Fe2O3 + 3 H2O
(c) Combustion - CO2 + 2 H2O → CH4 + 2 02
(D) Synthesis – 2 Na + Cl2 → 2 NaCl

Answer is B trust me

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.

Idk the answer imthink snail cant mate they dont lol
