Those of you looking at this in the future don't forget the quadratic equation!!!

You're in Chemistry with Prof. Kautz, right? Lol. :3

that is correct. The MM for Hs@ is 34.1. Closes to 5.02/0.147=34.15.

why is fe 2+ a better reducing agent then mn2+. ( I thought since mn2+ had a higher Eox it would be better)
Thermodynamics
Perfect. I do remember reading that before. Thanks so much for the help!

What is the temperature of a two-level system of energy separation equivalent to 300 cm^−1 when the population of the upper state is one-half that of the lower state? What does this "energy separation equivalent to 300 cm^−1" mean? I can get this far: n1 ...
Tutoring Question
I love this jiskha service so far. It's been extremely helpful, however I was wondering if there were pay services that offered a little more. Sometimes I don't get answers to homework problems I'm stuck on. I think it's harder to get help on some college level...

Calculate the entropy change in the surroundings when 1.00 mol N2O4(g) is formed from 2.00 mol NO2(g) under standard conditions at 298 K. I get +192 J/K. The book says -192 J/K. Here is my work, where am I going wrong? Standard Enthalpy of NO2(g) = 33.18 kJ/mol * 2 mol = 66.36...

GK, thank you so much. That was exactly what I was looking for!
Chemistry
The general formula for moment of inertia is: I = Sigma mi * ri^2 (mi is mass of atom, ri is distance to axis of rotation) In a diatomic molecule, the moment of inertia is I = ma*mb(ma+mb) * R^2 (R is distance between atoms, ma and mb are masses of two atoms) How is the diatom...
