Re: Graph

I feel like we probably aren't going to be using this graph since I didn't see it in the course reader anywhere and we aren't doing too much with phase changes yet, but this is helpful to visually understand the topics. Thanks!

Re: units for enthalpy problems

If you follow the units in the math that you are performing you should end up with the correct units, whether that is kJ or kJ/mol. Just make sure that if you are scaling and multiplying by mols you cancel the units and end up with kJ. I am pretty sure most of the time the units are kJ, but if the q...

There is also another important log rule you should know that states log(a/b)= -log(b/a), if it ever comes up in the practice finals.

Re: Roman numeral [ENDORSED]

How do you know if the roman numeral given is positive or negative, because if it's a positive three and negative three it's still written the same right? Just a roman numeral three? Do you have to look at the other parts of the compound?

Re: z<8 and z>8

z is an atom's atomic number and the less than and greater than have to do with whether the sigma bond is lower or higher than the first pi bond in the 2nd energy level in molecular orbitals. If z<8, than the sigma 2p bond is greater in energy than the pi 2p bond so it will be higher. And vice versa...

Re: Memorization Tips

I would say flashcards are one of the best ways to memorize the models. That is how I did it. Whenever you have some free time you can just run through the flashcards. For the models, I feel like a lot of it is being able to visualize the shape, so if you have a picture of the model in your mind and...

Re: Sig Figs Throughout Problems

Yeah, I would say always round to the correct number of sig figs at the end. If you round for every single calculation, you will end up with a number that could be very far from the correct answer because of rounding errors at every calculation. It also makes your answer more accurate, I think.
