Thank you!! That helps so much!

Can someone please give a description of the different types and reactions and how to identify them? I would appreciate it so much because I am so confused. Thanks!

Dear Dr. Lavelle, Thank you for your commitment to teaching and really helping us to understand chemistry. The many resources that you have gone out of your way to provide us with have really made the difference for my performance these past two quarters and I absolutely feel like I will be leaving ...

How do you know whether or not to add Pt(s) when writing a cell diagram from being given two half reactions?

What makes an alcohol secondary? How can you tell?

The "tert" is before "butyl" to show that the 4 carbon substituent comes from 1 carbon being connected to 3 other carbons rather than it just being a chain of 4 carbons associated with "butyl" by itself. Hope that helps!

When determining if something should be delta negative or delta positive or nothing at all, what exactly do you look at? Whether something is an electrophile or nucleophile? The transfer of electrons? I don't fully understand and would really love some clarification. Thanks!

I'm a little confused as to what Gibbs free energy means in terms of the reaction process/reaction profiles. Could someone clarify/explain? Thanks!

How do you know if the arrow for a mechanism should be drawn from the actual element or from the bond?

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

Is there a key for the practice quizzes in the course reader (I could not find the answers inside)? If not, will we have access to the answers at some point so that we can check our answers before we take our real quizzes?

Diondraya_Taylor_1C

That was the understanding I got as well but if anyone has a more concrete reason for why we can do that, it would be great because I'm afraid to employ that method for fear of being wrong

What are radicals in terms of Lewis structures and VSEPR formulas?

Diondraya_Taylor_1C

Yes, that is definitely helpful. Thanks!

Can someone please explain what the difference is between paramagnetic and diamagnetic molecules and how you can tell? I would really appreciate some clarification.

Diondraya_Taylor_1C

Oh okay, that helps. Thank you!

I'm a little confused. What exactly does it mean for a molecule to have a dipole moment? That the elements have formal charges other than 0?

Diondraya_Taylor_1C

I believe that Cr has a ground state electron configuration of [Ar] 3d^5 4s^1. So my understanding was that when it becomes Cr^+, the electron is taken from the highest energy shell. And being that the 4s is on the end and counts as the highest energy shell even though 3d appears after it, the elect...

It's midterm season, so think like a proton and be positive!

Workbook Self Test pg. 11 #8 "8. How many moles of CO2 (g) is produced when 500g of CaCO3 (s) is used to neutralize an acid spill? The equation for the reaction at 1 atm and 25 degrees C is: CaCo3 (s) + H2SO4 (aq) --> CaSO4 (s) + CO2 (g) + H2O (l)" In this sort of problem, when "neutr...
