Re: Electron Rearrangement

So basically, the attraction is mutual! However in class, it was always described as the electron deficient molecule "attacking" the electron rich molecule.

Re: ions and reaction orders

Hey! I am pretty sure they do? Was there a specific example you were thinking of? Because unless they are an intermediate and aren't included in the reaction mechanism, they should contribute to order.

Re: order of the compounds in a cell diagram

First off, the electrode is always furthest from the salt bridge. Also, in most cases I am pretty that if there is no electrode included in the reaction, the ions are listed in the order they appear in their reaction. However, even if they are out of order, you can tell where they lie based on which...

Re: Cell potential and free energy

So, I could try to explain it to you, but here are some resources that do a way better job than I could! http://chemwiki.ucdavis.edu/Analytical_Chemistry/Electrochemistry/Electrochemical_Cells_and_Thermodynamics"onclick="window.open(this.href);return false; http://chemwiki.ucdavis.edu/Analytical_Che...

Re: Sublimation in Action

I know iodine crystals and the chemicals in mothballs (naphthalene) are also common substances that sublimate!

Re: Energy of Orbitals

In the course reader, it states that "once 4s orbital is filled and e- enter 3d-orbitals, then 3d-orbitals become lower in energy than 4s." I believe that the electron configuration is the order in which the electrons are filled, but in actuality, the valence electrons are always in the ou...

Re: Homework Problem 1.23

Basically, an eV is the amount of energy transferred by an electron moved across an electric potential difference of one volt. This amount was derived from multiplying one volt (J/C) by the charge of a single electron (C), giving us 1.60218 x 10^-19 J.

Chemistry Community Points

If a student were to answer a question that does not follow the Chemistry Community guidelines (references book questions, etc.), and the question was deleted, would the student still be awarded a point for responding?
