Calculating enthalpy of formation with resonance
For part C of #67 in the chapter 8 textbook problems, we are asked to calculate the enthalpy of formation for benzene (C6H6) without resonance. For part D, we are asked to calculate the enthalpy of formation for benzene with resonance. How do I factor resonance into the calculations?

Reaction Enthalpy and Reaction Internal Energy
I'm still kind of confused on what the textbook means when it says, "The reaction enthalpy is less negative than the reaction internal energy for reactions that generate gases." Why would it always be less negative?

Re: VESPR
I don’t think ClO2 + would be trigonal pyramidal because it has 3 electron pairs about its central atom, 2 of which are bonded with oxygens and one is a lone pair. This would give it a bent shape. For a molecule to be trigonal pyramidal, I think it would have to have 4 pairs of electrons about the c...

Re: What are considered thhe e- in the outer shell?
For the electron configurations in the table, the s orbital is listed after the d orbital. Even if an atom, Cobalt for example, doesn’t have a full d orbital but has a full s orbital, would Cobalt use the electrons in the s orbital (since they are on the outside) to bond even though the orbital full...

Re: Sig Figs Throughout Problems
Is there a standard number of sig figs we are supposed to have for certain kinds of problems? Or does the number of sig figs in an answer vary with each individual problem?
