Why do chemists like working with ammonia?
Cuz it's pretty basic stuff.

Helium walks into a bar,
The bar tender says "We don't serve noble gasses in here."
Helium doesn't react.

Once I told a chemistry joke
There was no reaction

Laboratory retrievers!

Daniel Vo 1B

What happened to the man who froze to absolute zero?
He's 0K now.

Daniel Vo 1B

A photon goes through a hotel. They offer to take his bags. He says he has none, he's traveling light.

Daniel Vo 1B

If you're not part of the solution, you're part of the precipitate.

Daniel Vo 1B

Are you a high intensity photon? Because you put me into an excited state. <3 <3 <3
live lovelle laugh

Daniel Vo 1B

Are you *oxo* because you're the -one for me <3 <3 <3
live love lavelle

Daniel Vo 1B

When I'm with you I feel like unsaturated butter because you make my heart melt.

Daniel Vo 1B

Which fish is also an element?
Tuna -- 2Na

Two chemists walk into a bar. The first one orders "HIJKLMNO." The second chemists asks him what the [censored] does he mean. The first says, it's h to o, yah dingus.

Daniel Vo 1B

An ion dropped an electron on the street, his buddy asked him if he was sure
"Yeah, I'm positive"

Daniel Vo 1B

WHy do Chemists likE niTraTes so MucH?

CUz They'rE cheAper thAn DayRatES!!

Daniel Vo 1B

Reversible reactions won't be on the first test, will they?

Daniel Vo 1B

Are the reversible reactions the maximum work possible expansions?

Daniel Vo 1B

If anyone hits on you in chemistry
Just ask them
Are you a salt?
cuz NaBrO

Daniel Vo 1B

Liquid water just needs to cool down when it touches your skin--the resulting release of energy is actually quite low. Steam, however, needs to go through the process of changing phases on top of cooling down. The release of energy is almost ten times as much in this case, which explains why steam b...

Why are chemists good at sneaking up on people? They have the element of surprise!

Daniel Vo 1B

Why are photons atheist? Because they don't have mass :000

Daniel Vo 1B

Remember that since the placement of the atoms around the central atom will affect the polarity if it includes different electornegativies; some compounds can have both a polar and nonpolar configuration based on how the peripheral atoms are arranged.

Daniel Vo 1B

A few examples of elements that could make amphoteric compounds include Beryllium, Aluminum, Gallium, Indium and Arsenic.

Daniel Vo 1B

Are you made of copper and tellurium? Because you're pretty CuTe

Daniel Vo 1B

Hi, were we encouraged not to use the word "shift" in class? In which circumstances would it be appropriate?

Daniel Vo 1B

Be careful with the bond angles and the shape though; the bent shape with 1 lone pair and 2 lone pairs have a different angle in between!

Daniel Vo 1B

Yeah, so even though the pi bond is weaker, it does provide some strengh to the existing bond, so it results in a double bond that would be stronger the sigma alone.

Daniel Vo 1B

How would we know where to place the lone electron in a radical? Would it always be on the central atom?

Daniel Vo 1B

When we have to find the structure and shape of an ion, where does the extra electron go? Would it have several different shapes like how Lewis dot structures have several resonance structures?

Daniel Vo 1B

How do you connect the Shrodinger Equation to the actual physical representation of the electron orbitals? Is that outside of the scope of this class?

Daniel Vo 1B

Hi, sorry, I'm kind of struggling to understand how the equation works; can someone explain the equation in physical example? Like if one variable grows bigger, what happens to the others, and what would that mean?

Daniel Vo 1B

I'm pretty sure that if you change the wavelength, you do affect the ejected electron. As the wavelength shortens, you end up with a higher energy from the photon, which in turn transfers a larger kinetic energy to the ejected electron. The number of electrons set off by one photon is always one tho...

Daniel Vo 1B

I've read that the electric and magnetic fields of the light vibrate at right angles to the direction the light wave is moving, and because it is made of electric and magnetic fields, it, unlike other waves, does not need a medium to travel through. What this means physically is beyond me, sorry.

Daniel Vo 1B

Hi, sorry this might be a dumb question, but for the homework are we doing the same "pick four problems from the set" again?

Daniel Vo 1B

How I would go about that is to set up the equation between molarity, moles and volume. Starting with 10. mL (.010 L) and .10 mol L-1, we can set up .10 M= .0010 moles / .010 L So that'd be the initial equation. The independent variable we want to change is the volume, which we double 90 times (2^90...

I think the CuSO4*5H2O is a hydrated version of the salt, so while it isn't just a solution, it does definitely have water in it. I kind of imagine it as the Cu and SO4 molecules breaking up slightly enough to allow the H2O to bind with it. Once you've poured in 250 mL though, it's definitely a solu...

Daniel Vo 1B

I'm pretty sure if it's asking how many atoms are in a molecule, it would be asking you to count up the number of atoms present in the molecular formula (for example, H2O has three atoms in a molecule, 2 hydrogens and 1 oxygen).

Daniel Vo 1B

Part of the reason why Avogadro's number comes up a lot is that it's the number of atomic mass units that would weight 1 gram; if you had 1 mole of just neutrons you would have the equivalent of 1 gram. In a way, you can think of it as another conversion factor, like 12 inches in a foot, 6.022*10^23...
