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

Why do chemists like nitrates so much?
They're cheaper than day rates.

Emilia z

Have you heard the one about a chemist who was reading a book about helium?
He just couldn't put it down.

Emilia z

Do you have 11 protons? Cause you're sodium fine.

Emilia z

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

I know a guy who cooled himself to -273.15C.
He was 0k.

A neutron walks into a bar and asks the bar tender how much for a soft drink. The bartender replies, "for you, no charge!"

Emilia z

What do you call a tooth in a glass of water? a one molar solution

Emilia z

Two men walk into a bar. the first man orders H2O, the second man asks for "H2O too". the second man dies.

Chemistry Community is such a great resource so I only try to post jokes periodically

Emilia z

^ I slapped my Neon that one

Emilia z

Wow, chemistry jokes are Sodium funny

Emilia z

I try to only tell chemistry jokes periodically

Emilia z

Once i told a chemistry joke... but there was no reaction

Emilia z

If a king farts is it a Nobel gas?

Emilia z

Why do white bears dissolve in water? they're polar

Emilia z

Every dipole has its moment

Emilia z

What is a cation afraid of? A dogion

Emilia z

I would write a funny chemistry joke, but all the good ones Argon

Emilia z

Don’t trust atoms, they make up everything

Emilia z

The change refers to what change is happening to that species, and we use x because we don’t know the exact amount that changes (either taken away or added/created)

Emilia z

Yes that sounds right

the test takes place during your discussion section starting Tuesday of next week. Also, I had Caram last quarter and we had weekly quizzes each worth 5 points total but he would write the number of points each question was worth next to the questions so we knew how much weight each question carried...

Emilia z

Technically yes, but that would be the correct way to solve for the pKb of an acid given the pKa

Emilia z

It looks like this question is just testing you on your ability to understand the equation for K, and not necessarily solve for any value. Therefore the solution is just K = pressure of the products / pressure of the reactants, since some of this is unknown you substitute 'x' for those pressures and...

Emilia z

I believe you can usually figure out whether or not to use Kp or Kc based on the information given surrounding the chemical equation because both can be used for gases but sometimes certain information is required depending on the K you are asked to use.

Emilia z

Usually if you are solving a problem involving both K and Q, you will be given a value for K for which you will compare the value you get for Q to. This is because the chemical equation you are given is not necessarily at equilibrium, and to find this out you compare your K and Q values (if they are...

First you have to use an ICE table to find the concentrations at equalibrium (to get your quadratic you should use the equation for K and your given K value), then you can use those numbers to figure out the percent that decomposed for part b
