Learn it just to be safe, from my understanding if it's in the homework problems it's fair game for the final.

In quiz 3, there was a question about drawing three different cyclic isomers for C5H10. How do you do this?

A photon checks into a hotel and is asked if he needs help with his luggage. He says, "No, I'm traveling light."

When balancing redox half reactions and using e- and H+ to even out the charges on both sides of the equation, why do the H+ and e- not cancel each other out if they are on the same side of the equation?

Not sure if this answers your question entirely, but I believe the purpose of the standard hydrogen electrode (SHE) is to have a basis to compare all other electrodes to.

Laine Gruver 3C

If I'm correct, an isothermal reaction means that the temperature remains constant, whereas an adiabatic process implies that no heat is exchanged between a system and its surroundings.

I noticed in some of the textbook problems that for enthalpy, they seem to use both kJ/mol and kJ interchangeably. Can anyone help explain this to me?

Laine Gruver 3C

Does anyone know if on a test we would be given the standard enthalpy of formation or specific heat capacity for molecules we're working with? I'm assuming we would be given ones for more obscure molecules but I wasn't sure if we needed to memorize the more common ones.

There's truly no such thing as an isolated system, only very close to one, so I think you always have to read in between the lines as to what the problem is getting at.

We have to include all the essential parts of the reaction, and the reaction would not occur without water accepting a proton to become a hydronium ion.

Does anybody know if the list of strong acids in the course reader is exhaustive?

When finding the hybridization of a molecule like benzene, C6H6, or any other molecule with some sp hybridization, why is it that we don't say s^2 when we say p^2, p^3, etc?

Laine Gruver 3C

The 'p' refers to the p-block of the periodic table, with that specific type of orbital. As far as I understand, x, y, and z represent the different orientations that a p-orbital can have. I've included a picture that represents the orientations and where their nodes fall.

I only just looked this up on wikipedia, so someone please correct me if I'm wrong, but it says that the formula is that the nth shell can hold up to 2(n^2) electrons, so that would mean it is possible to have more than 8 valence electrons.

To add onto this, what is the policy like for partial credit? i.e., if a problem has multiple parts and we make an arithmetic mistake in an early part that affects the subsequent answers, will we receive absolutely no credit?

I'm not sure if this will be helpful to you, but I thought it was helpful in figuring out how to name compounds: http://www.chemteam.info/Nomenclature/H ... pounds.jpg
