Hello,

I was working on question 9B on the Winter 2015 final and they named the OH functional groups as hydroxy functional groups instead of alcohols? Can someone explain why this is and how we can tell the difference? Thanks!

Hey everyone,

Why is is that the Faraday constant is not included in the equation that the solution uses? Instead, they only use the n in the equation. Thanks!

Hi Sarahi, Aryl carbanions are aromatic (ring) compounds made of carbon that have lost a hydrogen and now contain a lone pair of electrons. They are sp2 hybridized. Alkyl carbanions are non aromatic, so the carbons are bonded in a chain, and the carbon has lost its bond with a hydrogen and now has a...

I cringed so hard but here it is

If H20 is the formula for water, what is the formula for ice?

H20 cubed

Hi there,

Intermediates are not included in the overall rate law because intermediates are not final products. So because intermediates are not observable, they are not included in the rate law that is determined experimentally. Hope that helps!

Hi guys,

I was doing question 15.19 and I was having trouble finding the order of the reaction of B. According to the solutions manual, the reaction is second order in B, but I don't understand what steps they took to get that answer so any clarification would be much appreciated. Thanks!

Hello,

I was wondering why and how the temperature is converted from degrees celsius to K on question 2 from the 2016 midterm? I thought that you converted degrees celsius by adding 273 K to it, but the questions says that -70 degrees celsius is the same as -70 K..? Thanks!

Can someone please explain why on #5 the answer has 2NH3 on the product side? When I did the question and canceled everything, I divided 2NH3 by 2 so that it would be the same as in the target equation N2H4 + H2 = NH3. This gave me an enthalpy of -105.1kJ/mol, instead of -151 kJ/mol. Thanks

In the question, it mentions that Kr is a monatomic gas and I was wondering what exactly is a monatomic gas? I checked in the textbook and it mentions that the molar internal energy of a monatomic ideal gas is 3/2RT. Basically, I was wondering why the internal energy formula is different for a monat...

Hi, I had a question that I thought would be relevant to this topic. I was simply wondering whether or not elements that are not contained within the brackets or are directly bonded to the transition metal (like ligands) could also be factored into the coordination number? Thanks!

Wow this was really helpful! Thanks for making it!

How is it possible to have bond orders of 1.5, 2.5, etc? Does it have anything to do with resonance structures?

Hey Yuni, When referring to the ground state electron configuration of an atom, it simply means it is the electron configuration of an atom at its lowest energy level. In contrast, an atom in an excited state has absorbed additional energy. I have added a link below that might help you out a bit bet...

Hey there, I just wanted to share this diagram with you because it really helped me memorize the trends of electron affinity and electronegativity on the periodic table. I hope it helps you put things into perspective! http://2012books.lardbucket.org/books/principles-of-general-chemistry-v1.0/sectio...

Ariana, I believe that only the final answer has to have the correct number of sig figs and you use exact calculations throughout the problem to make sure your answer is accurate, but anyone feel free to correct me if I'm wrong.

So, just to clarify, you got 7.55 x 10^-20 by using E=hv and plugging in the given frequency? Also, can you explain how canceling the negatives works out to n=6? Thanks!

Can you explain the concept behind #18? I thought that the work function was exactly the same as the threshold energy (energy needed to remove electrons) so I don't quite understand what is being done. Thanks
