Generally, how does someone know whether a molecule is Z or E just from the line structure?

Thank you for being such a great professor! Chemistry will be different without you next quarter.

"Neo" is not just limited to cycloalkanes. There should be a pretty good drawing delineating neo alkanes in the book.

What types of reactions do they sell at Whole Foods?
Organic ones hahahahahahhahahahaha

Doing the homework questions in the textbook and going over the examples throughout the chapter are, to me, the best ways to prepare for a quiz. Go over the material with friends too!

I need 2... moles.. one for plug and one for the load

Kevin Le 1L

"n" typically stands for the number of moles.

Get yourself a friend who is down to hang out with positive entropy haha haha get it, like someone who likes to hang out spontaneously haha

Like the others said above, q and delta H are interchangeable only when a system is under constant pressure. However, we can calculate q using delta H during phase changes. q = (mass)(delta H at a phase change).

Dude that is telling joke: What did the chemist say to the other chemist?

Dude receiving the joke: lmao wat

Dude that is telling joke: We're both chemists

lol

Because strong acids and bases dissociate completely in water, you could use simple stoichiometry to determine the concentration of H3O+ or OH-. Because weak acids/bases don't dissociate completely in water, you're going to need to use the equilibrium constant.

How did the chemist get in prison?
He was charged with a salt and battery hahahahhahah

The coordination number refers to the number of atoms directly bonded to the transition metal. If one of the atoms shares a double bond with the transition metal, it still counts as 1 when finding the coordination number.

Though it's definitely possible to take Chem 14B and 14BL in the same quarter, I think it's actually quite rare that people take them in the same quarter. I've heard people start LS 2 winter quarter and hold off 14BL until their second year. Ultimately, if you feel sure enough with your understandin...

The t-shaped and trigonal pyrimidal shapes both have the VSEPR formula AX3. How does one know whether a molecule is t-shaped or trigonal pyrimidal?

What did the atom say to the other atom?

We're both atoms haha! :^)

Hey guys!

Why did the chicken cross the road?
To get to its chemistry lecture!

ha ha ha hahaha ahhahahahahhahahhahahahahahaHAHAAHhahhah
