It is an electrophile because the Al wants those 2 missing electrons in order to have its stable, full octet.

I think you will be fine regarding the derivations, you will not have to know them as most of the equations needed will be given.

It can be either kJ/mol or kJ, just keep in mind the coeffecients of the products and what the question wants you to give as a final answer.

You will most likely be using them in weak acid and base problems to find their equilibrium concentrations; usually some indicators that you will have to use an ICE table is that they are asking for the concentrations and they have provided you with a "k" value (kb or ka).

Your final gram calculation for the NaOH is 1 decimal place off, but your final percentage is still correct...weird, must of just had a typo or something. *thumbs up*

Examples: Weak acid and its conjugate base: CH3COOH + H2O<--> (CH3COO-) + (H30+); in this example, acetic acid (CH3COOH) loses a proton (H+) and becomes its conjugate base: an acetate ion. Weak Base and its conjugate acid: NH3 + H2O<--> (NH4+) + (OH-); in this example, ammonia (NH3) gains a proton (...

I believe p means something along the lines of "power of (hydrogen)" or I have also heard it used as "potential of (hydrogen)."

Think of it like this: generally, single bonds are sigma bonds and each additional bond (i.e. within double and triple bonds) is a pi bond (double bonds have 1 sigma bond and 1 pi bond, triple bonds have 1 sigma bond and 2 pi bonds).

I don't know the exact length of a triple bond, but it's not that important to know the exact length of single, double, and triple bonds as these lengths vary between molecules. What is important is that bond length decreases as it goes from single>double>triple.

I asked a couple of my friends if they wanted to hear a good sodium joke. They said Na.

Ryan Petrecca 1L

I got all these good chemistry jokes, I'm scared they won't get a good reaction :'(

sodium sodium sodium sodium sodium sodium sodium sodium Batman!....
