Potential/Residual Entropy

I noticed on page 29 of the course reader it mentions that the equation S = kb ln W is the equation "to find Potential/Residual Entropy. This ignores thermal entropy." I was wondering what that meant because that is the only equation for entropy given? Will we only need to find potential e...

First Law of Thermodynamics

Is it important to know the first law of thermodynamics? How would it be used in a question?

Primary, Secondary, ect. Carbons

When/how will knowledge of primary, secondary, tertiary, and quaternary carbons be used in the class? I haven't seen any problems on them.

Strategies for studying for the final

My strategies for studying for the final are to create a conceptual study guide from the course reader, and to do the practice finals and work to understand each question and step. Anyone want to share how they are studying?

What is covered in Quiz 3

Does Quiz 3 cover Thermodynamics and Kinetics of Organic Reactions (Ch 4.1-4.4 Organic Chemistry and pgs.79-88 of course reader) and Hydrocarbons and Functional Groups (Ch 1 and 2 Organic Chemistry and pgs. 89-103 of the course reader)?

2015 Final Q7A

For the 2015 final Q7A the second to last part asks, A patient died due to a blood pH of 6.5. Is this the result of acidosis or alkalosis? Based on the above overall reaction what was a possible cause of this low pH? and the answers are Acidosis and Excess CO2 in the bloodstream. My question is why ...

When making an M.O. diagram of 2 elements, where one has z<8 and the other one has z>/=8 how do you know which diagram t

When making an M.O. diagram of 2 elements, where one has z<8 and the other one has z>/=8 how do you know which diagram to use? For example in textbook problem 4.57b I made an M.O. diagram of NO+, and in the solutions manual they used the z<8 M.O. diagram, even though oxygen has an atomic number of 8...

M.O. Diagram Textbook Problem 4.57

Question 4.57 in the textbook asks us to draw the M.O. energy level diagram for N2 and label the energy levels according to the type of orbitals from which they are made. I usually include labels in my M.O. diagrams anyways, but in the answers it shows the M.O. diagram with dotted lines and the labe...

Polar/Non Polar 4.25d

Hi for chapter 4 question 4.25 we are supposed to write a lewis structure and determine whether or not the molecule is polar or non polar. For part d I drew the lewis structure for SF4 and I thought that it would be nonpolar because there are 4 dipole arrows going in four different directions, but a...

Balancing Chemical Equations

I understand the main concepts of how to balance a chemical equation, however for me when the numbers get large and it seems like you're in an endless cycle of balancing the number of mols of one element just to make the mols of another element unbalanced again. Once I know what the correct answer i...

I have several questions about this exercise. 1) How are we supposed to find the molar mass of chloride in this metal if chloride isn't even included in its molecular ...
