Which of the following mole ratios corresponds to the mole ratio of silicon tetrafluoride to hydrofluoric acid in the reaction:
SiO2 + 4 HF (aq) → SiF4 + 2 H20 (aq)?
O 1:4
O 1:2
O 4:2
O 1:1

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.

Where is the following?

The correct answer would be b) volume versus temperature, because they are also directly proportional.
