if you attempt to react 6 moles of PCI, with 20 moles of H, O, what is the limiting reactant and how many moles of HCI can be made? PCI, + 4 H,0 - H, PO, + 5 HCI

"standard molar enthalpy:

h2o ( liquid water ) : - 285.8 kj/mole

h2o ( water vapor ) : - 241.8 kj / mole.

δhrxn = - 241. 8 - ( - 285.8 )= -241.8 + 285.8 = 44.0

answer: 44.0 kj"

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
