Given the balanced reaction below, If 0.10 mol of BF3 is reacted with 0.25 mol H2, which is the limiting reactant? 2 BF3+ 3H2=2B+ 6HF

A- .40 mol Hf
B- .75 mol Hf
C- .50 mol Hf
D- .30 mol Hf​

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.

We first assume that this gas is an ideal gas where it follows the ideal gas equation. the said equation is expressed as: pv = nrt. from this equation, we can predict the changes in the pressure, volume and temperature. if the volume and the temperature of this gas is doubled, then the pressure still stays the same.
