Re: Naming [ENDORSED]
I'm a little confused on what cases to use prefixes like iso and neo rather than the normal numbering I also have this question - although I understand that you use iso- and neo- when you see specific groups, I can't quite understand how to identify them and when to use iso- or neo- as opposed to o...

I believe the iso- indicates a structural connectivity of (CH3)2CH- , as indicated in page 9 of the Ochem green booklet.

Re: General Rate Question
I would think that using different metric prefixes doesn't really make a difference (as long as in the end, it is correctly stated) but if the question uses different units (ex atm vs pascals, kelvins vs celsius) I agree that you ought to give the answer in the same units as you started with in the ...

Example 14.10 Using Nerst Equation to find Concentration
Hi all,
I'm having some difficulty understanding how the equation in example 14.10 (page 589 of textbook) was set up. Could someone walk me through the process step by step of how to know that the cell reaction is Ag(s) | Ag + (ag, L) || Ag+ (aq, R)|Ag(s) ? Thanks!

Re: Sig figs
To add to the above, the textbook (6th edition) has notes for how to do sig figs on pages A5 and F10 of the appendix. Specifically, rules for logarithms and exponentials are on page A6 that basically say that the answer should have the same number of sig figs as the original number. Hope that lookin...

Re: Q and -Q
Hi, Just to continue off the other response, this is basically the first law of thermodynamics. It states that "the internal energy of an isolated system is constant"; the universe can be considered an isolated system. Thus, we can say that (as Stephanie said) energy is always conserved, s...

Themodynamics: Systems at Equilibrium [ENDORSED]
Hi, I was a little confused as to the note on page 22 of the course reader that stated that thermodynamics is the study of changes in energy for systems in equilibrium, and then that the change in work would thus depend on small fluctuational biases of things like the pressure or volume? How does on...

Re: Enthalpy vs Energy
I think this is a complicated question too! To add to the above answer by Emily, I think it helps to remember that increase or decrease of heat in the system is essentially energy going into or out of the system, respectively, in the heat form. Enthalpy describes this amount of heat released or abso...
