Axial Bonds and Equatorial Bonds

Hello,

Can someone tell me the difference between the Axial and Equatorial bonds, because I am kind of confused why there is a difference. To me they look the same. Is it because the Axial bond is vertical while the equatorial bond is horizontal?

Thank you in advance,
Sylvester :)

Standard Gibbs Free Energy of Activation

Hello,

I was just wondering why the Standard Gibbs Free Energy of Activation is always going to be a positive value?

Thank you in advance,

Branched vs. Unbranched

Hello, I am not confused on what the difference is between the two structures of branched and unbranched , but what I am perplexed about, is what Dr. Lavelle would even ask on an exam. Does he have a preference on drawing the molecular formulas branched or unbranched? Or will he specify, if he wants...

Limiting Step

When we are given problems that involve the fast step and the slow step, how can we tell which step is the limiting step?

Thanks in advance,

Awesome Chemistry Joke :)


A neutron walks into a restaurant and orders a couple of cokes. As she is about to leave, she asks the waiter how much she owes. The waiter replies, "For you, No Charge!!!"

Balancing Charges?

Hello,

I know that Dr. Lavelle went over this on Friday, but I am kind of confused on how to balance the charges in order to make sure that they are all balanced on both sides of the reaction. Can some on explain this to me briefly?

Thank you in advance,
Sylvester :)

Why Does Steam Cause Severe Burns?

Hello, I was looking back at my notes, and I kind of got confused on one of the questions on the Course Reader. It asked, Why does Steam Cause Severe Burns? I know that it has to do with the steam taking more energy to get to the degree of your hand than water does, but can someone elaborate on this...

Isothermal Objects

Hello,

I was looking over my notes, and when I got to the definitions of what an open, closed, and isolated system are, I began to wonder. What would something that is Isothermal (Constant Temperature) be considered? Is it an open, closed, or isolated system?

Thank you in advance,

Sylvester :)

Positional Entropy

Hello, I believe that I have a good understanding of what Positional Entropy is, and how it is related to the Second Law of Thermodynamics, but what I do not understand is why it does not take into account Thermal Entropy ? I know that Dr. Lavelle went over an example that had to deal with degenerac...

Bar Vs. Atmosphere

Hello, I was just wondering what units were going to be used more prominently in this course (Chem 14B), because when I did the reading of chapter 8, I noticed that when I got to section 8.15, they started to use both the units of 1 bar as well as 1 atm to describe the pressure for the change in ent...
