Re: Midterm Grades

Yeah, I would expect them to come out at the end of this week considering they don't want test scores to be released before everyone has taken the test.

Lavelle's Jokes

If you're anything like me, you LOVE Lavelle's end of lecture puns. I wanted to make a page where we can collect cheesy jokes to make Dr. Lavelle chuckle or use in office hours :)

Re: 1A.15

I think Rydberg's constant should be a positive since in this specific problem we're trying to figure out which n the electron is going to from the ground state of n=1 which is gaining energy not losing it. We only do a negative when were trying to figure out the energy that is emitted from the ele...

1A.15

In the ultraviolet spectrum of atomic hydrogen, a line is observed at 102.6 nm. Determine the values of n for the initial and final energy levels of the electron during the emission of energy that leads to this spectral line. I found the frequency but when I plug it into the Rydberg formula I'm not ...

Atomic Spectra Module Question 39

Calculate the wavelength of the radiation emitted by a hydrogen atom when an electron makes a transition from n = 4 to n = 2.

How would we do the proper conversions to get the wavelength considering we already know the energy per photon from the previous question?

Yes, you should 100% use a calculator. A key thing that most people forget is parenthesis so don't forget!

Re: L.39

The crucible is the vessel that allows for this reaction, however, the mass of the product is all we want to look at when answering this Empirical Formula question. Subtracting 26.45g (mass of crucible) from 28.35g (mass of crucible + mass of product) means that we are left with just the mass of th...

A 1.50-g sample of metallic tin was placed in a 26.45-g crucible and heated until all the tin had reacted with the oxygen in air to form an oxide. The crucible and product together were found to weigh 28.35 g. (a) What is the empirical formula of the oxide? (b) Write the name of the oxide. To get th...

It's always better to be safe, especially in a chem class. You should definitely check to see that it is balanced before moving on.

Yes they're the same thing. Mol is just a shorter way of saying mole. I don't know why it's that hard to add the "e" but I guess it is ¯\_(ツ)_/¯

Re: Determining Limiting Reactant

I'm pretty sure this is the only way but if you want to hear another explanation here is my attempt. You can find the limiting reagent by calculating the amount of product that can be formed by each reactant; the one that produces less product is the limiting reagent

This may sound dumb but how do you convert from grams to moles and also how do you convert from millimoles to moles? I'm pretty sure I'm just overthinking it.

Avogadro's constant is 6.022x10^23 in case you didn't know.
