Re: Post All Chemistry Jokes Here
A proton and a neutron are walking down the street.
The proton says, "Wait, I dropped an electron help me look for it."
The neutron says "Are you sure?" The proton replies "I'm positive."

Re: Strategies for studying for the final
I use a similar method (continuing to do past finals and midterms). I find that the only way for chemistry to really stick in my brain is for me to continuously do problems until I can solve them completely on my own.

Organic chemistry is difficult. Those who study it have alkynes of trouble.

Question 4.30 in the organic chem book
Question 4.30 asks if a reaction can occur at room temperature if the known activation energy is 125 kJ/mol. Apparently, the answer is no, can someone explain why?

Re: Naming ligands and writing ligands alphabetically? [ENDORSED]
In general, H20 tends to go at the end of the ligand, regardless of alphabetical order. But alphabetical order doesn't matter when writing out the formula; it only matters when naming the compound.

Re: Strong/Weak Acid/Base
So basically, the strong acids are: HCL, HBr, HI, HClO4, HNO3, H2SO4 and the strong bases are: LiOH, NaOH, KOH, RbOH, CsOH, FrOH, Be(OH)2, Mg(OH)2, Ca(OH)2, Sr(OH)2, Ba(OH)2 As long as you remember that halides combine with H+ to form strong acids and alkali metals/alkaline earth metals combine with...

Difference between z>8 and z<8
I'm a little confused on what the difference is between atoms with z>8 and z<8. How and why does this affect the molecular orbital diagram?

Re: Linear vs. Bent Molecular Shape
I find it easier to think of it like this: the extra lone pair on the chlorine repels the electrons on the oxygens, which causes the oxygens to try to move as far away from that lone pair as possible while still maintaining distance between each other. This causes the molecular shape of ClO2 to be b...

Re: Breaking the Octet Rule
I recall Dr.Lavelle saying that elements in period 3 and/or group 13 of the periodic table tend to be exceptions to the octet rule. As such, elements like boron, aluminum, sulfer, and phosphorus tend to be exceptions to the octet rule. I hope that helps!

Re: HW Prob. Ch1 #25 [ENDORSED]
According to the peer facilitated learning session I attended last night, the book implies that the answer you get in part a is actually the number of joules in one atom. Part b then asks you to convert the joules per atom into just joules. So, 3.37x10^-19 J/atom is the energy/atom you should have c...

Re: All students read this sig fig post [ENDORSED]
If there is a multistep problem, do we maintain four significant figures per step, even for the following step? For example, if part A requires an answer with only four significant figures (example: 1.178), and part B uses that answer to solve for another variable, should we use 1.178 or the extend...
