HW 2D13

Could someone help me with this problem?
it is asking to list the following molecules/ions in order of decreasing bond lengths and explain your reasoning:
a) the CO bond in CO, CO2, CO3 2-
b) the SO bond in SO2, SO3, SO3 2-
c) the CN bond in HCN, CH2NH, CH3NH2

from my understanding, you would only use the Rydberg EQ when you are looking for the change in energy when an electron moves from one energy level to another.

you can turn in just 5 or all of them, I don't think it matters. the TA will probably just grade the first 5 if you turn all of them in.

Re: Rydberg equation [ENDORSED]

i understand why the first equation prof. lavelle showed us is negative (-hR/n^2). when he derived the second equation (-R[1/n1^2-1/n2^2]) he kept the negative in front but my TA showed that equation as positive. Which is correct?

Because it differs so much according to different tables, I think it will be fine if you just remember 700 to 400

Because each question is worth so many points, it would be wise to show at least the basic steps that you used to get to your solution.

Re: Help on HW: Fundamentals G5

I would start by using the equation for molarity and go from there: Molarity = number of mols/volume for part a, we can find the numbers of mols of Na2CO3 by taking 2.111 grams and dividing it by the molar mass of Na2CO3, which is about 106. Hence, we get 2.111/106 = 0.01992 mol Na2CO3. To find the...

Re: Solving for Volume G.5 a)

So this problem is asking us to determine the volume of the solution should be transferred into a flask in order to obtain 2.15 mmol of Na+ . Importantly, this is not a dilution problem. Therefore, we won't be using the M1V1=M2V2 equation. The molarity of the solution won't be changing when we tran...
