Homework Statement I need to calculate the activation energy (barrier of rotation) of an amide bond. I have NMR spectra at various temperatures. I know that once I have the rates I can do an Arrhenius plot to find the activation energy, but I'm having trouble with the ``finding the rates''...

We used 3% TMA?

This is a really good question that I can't answer but I hope someone can. Maybe it has to do with hybridization? By trigonal planar I'm assuming you mean that the molecule has trigonal bipyramidal geometry but places the lone pairs at 180 from each other?

Homework Statement I have a spectra of the NMR, I'm just confused on where to `zero' the spectra at? Homework Equations The Attempt at a Solution There are two peaks around zero in the spectra (one is bigger than the other but not by much). Also the two peaks are much much smaller than the...

Homework Statement Assign J values for P and R branches of H35cl, H37cl, d35cl, and d37cl compounds. Homework Equations The Attempt at a Solution I have a fundamental IR spectra I did on and HCL/DCL compound. I'm extremely confused how to assign J values. I've been looking online...

Nevermind y'all, was a silly mistake. I can easily do a one sample t test

Homework Statement You use a standard gram weight of known weight (x) to check the accuracy of a balance. For one balance, this standard is weighed 3 times yielding the following values; a, b, and c. Calculate the 95% confidence limit for the mean Homework Equations general statistics...

Hi I have a question I was wondering if y'all could clear up. Let's say I have two metal cations, Iron (III) and Manganese (II). Will binding them to an anionic ligand lower their reduction potentials (making each a better redundant) and if so why? Is it because the anionic charge of the...
