I asked my lab partner for sodium hypobromate, but he said Na Br O.

Catherine K 2B

Take all the bad chemistry jokes and Barium

Catherine K 2B

If Avogadro calls, tell him to leave his number

Catherine K 2B

Are you made of Copper and Tellurium? Because you're CuTe!

Catherine K 2B

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

Catherine K 2B

When is the chemical formula for banana?

BaNa2

Catherine K 2B

Oxygen and Potassium went on a date...it was OK.

Catherine K 2B

Do I have good chemistry jokes?

NaH

Catherine K 2B

Why did the attacking army use acid?

To neutralize the enemy's base.

Catherine K 2B

That was sodium funny!

I'm slapping my neon that one!

The term "standard" when used to describe a reaction means that it is occurring at standard temperature and pressure.

Catherine K 2B

For this problem, you can use the formula ΔH = Ea(forward) - Ea(reverse) !!

Catherine K 2B

If volume and pressure are constant, Gibbs free energy can be used to measure the maximum amount of work in a system.

Catherine K 2B

You can use 1/(M^(overall order -1)S) to determine K units

Catherine K 2B

The oxidation number of O3 is 0!

Catherine K 2B

The oxidation number of O3 is 0!

Catherine K 2B

Delta U is equal to 0 under isothermal conditions.

Catherine K 2B

Intermediate species are formed and used in the reaction, so they will not show up as part of the products of the overall reaction. This means, when calculating the rate, they should not be taken into account.

Catherine K 2B

Zero Order: M/s
First Order: 1/s
Second Order: 1/(M*s)
Third Order 1/ (M^2*s) or 1*M^-2*s^-1

Catherine K 2B

You must take into account the orders for each reaction. The sum of these orders is the overall order of the reaction.

Catherine K 2B

The best way for me to think about it is that exothermic reactions have a negative change in enthalpy because they release energy and endothermic reactions have a positive change in enthalpy because they require energy to occur.

I had to make sure that I had downloaded Respondus to the right folder on my computer! It kept going straight to my desktop and wasn't available but once I made sure it went straight to my downloads on my computer it showed up under applications.

Catherine K 2B

Pi bonds cannot rotate, but all sigma bonds can

Catherine K 2B

I don't trust atoms...I heard they make up everything.

Catherine K 2B

What kind of fish is only made up of two sodium atoms?

2Na

Catherine K 2B

I tell bad chemistry jokes because all the good ones Argon.

Catherine K 2B

I try to tell chemistry jokes but there is no reaction.

Catherine K 2B

Helium is a laughing gas...He He He

Catherine K 2B

A: "Want to watch me mix oxygen and potassium?"

B: "OK"

Catherine K 2B

I saw oxygen and magnesium holding hands and I was like OMg.

Catherine K 2B

How often should you tell a chemistry joke?

Periodically.

Catherine K 2B

Can someone please check my work for this problem? Based on the feedback from achieve I think I'm doing it correctly. Please correct me if I’m wrong!
