PKa = -logKa was also mentioned as well, but pretty sure that won't be on the final because that's 14B material?

melodyso1K

Agreed. And maybe (p = -log) as well?

This was said today during one of the review sessions ^^

Also, the element in the middle is the one that has to make the most bonds!

melodyso1K

Yes, it's interchangeable! In the review session today for the #3 on the practice exam we used "bent" and "angular" interchangeably.

melodyso1K

It does. I asked about this in office hours before, if all your points add up to 250 points (50% of the overall grade), that is a C-

Also, the shorter the bond length the stronger it is.

Q: What do you do with a sick chemist?
A: If you can't helium and you can't curium, then you may as well barium.

I thought this was pretty interesting so I looked into it a bit:

CO2 is the biggest factor in the acidity of water. In the dissolved state in water CO2 + H2O <=> H2CO3. So as CO2 levels increase around Earth and H2CO3 increases, pH levels decrease.

Hope this answers your question!

I recall our section saying we only going up to sp3 as well back in week 8.

These were all very great and very helpful, thanks everyone!

melodyso1K

This chart is indeed helpful, thanks for sharing!

melodyso1K

We made a similar chart in discussion too. I want to point out that I believe our TA mentioned something about the angles being less than 109.5 in some cases, I'm not exactly sure why or in what instances, but I think he mentioned lone pairs. I also think Lavelle said that we don't have to know the...

Weak acids are incompletely ionized in a solution, in the example in lecture today it says to setup an equilibrium to calculate concentrations

melodyso1K

The example I wrote down for weak acids was CH3COOH molecules and a small portion of acetate ions, CH3COO-

This was the announcement Professor Lavelle gave for Test 2: Test 2 covers material covered in Chapter 1 up to the end of 1.5. (wave and photon properties of light; Einstein equation; photoelectric effect; Bohr frequency condition; atomic spectra (electronic transitions); wave and particle propertie...

How often do I tell chemistry jokes? Periodically.

I don't think too many people finished on time for Test 1, at least to my understanding. Should start preparing for 8 questions in 40 minutes from now on.

The email says that that Chapter 1 homework problems: 3, 5, 7, 9, 11, 13, 15, 21, 23, 25, 27, 33, 37, 39, 41 should be helpful

The Planck's constant relates energy in a photon of electromagnetic radiation to the frequency of that radiation. The constant is approximately 6.626176 x 10^-34 J/s and can also be shown as "h" in h=E/v.

That time doesn't work for me, sorry! Hope everything works out

What time is the 1L discussion?

Argon and Neon walk into a bar during the French Revolution. The bartender said "We don't serve noble gasses here"

melodyso1K

Option A is incorrect because speed is constant! :D
