Looking through this link really helped clarify strain concepts for me:

Re: Chemistry Jokes
The optimist sees the glass half full.
The pessimist sees the glass half empty.
The chemist see the glass completely full, half in the liquid state and half in the vapor state.

Re: Chemistry Jokes
Who doesn't love a good chem pun? Apparently a lot of people.
I mean, I am always trying to cell a good electrochem joke, and it is SHOCKING that some people do not appreciate the joke. They reVOLT against electrochemistry puns, and because of that they burn that SALT BRIDGE with me.

Re: Types of Salt Bridges
A good, efficient salt bridge is something that is soluble in water (so you can get ions into solution) and relatively inert (so that either ion will not react with electrodes or ions in the two solutions.)

Re: Hess's Law
A state function or property describes the equilibrium state of a system. For example, enthalpy is a state quantity because it describes an equilibrium state of a thermodynamic system.

Re: Naming compounds
You use bis, tris, etc when the compound is polydentate meaning the ligand has more than one bonded atom. Monodentates use the prefixes di, tri, tetra etc.

Re: Equilibrium constants
This is because they do not affect the reactant amounts at equilibrium in the reaction, so they are thrown out and kept at 1.

Re: Why Can't T-shaped Molecules be Trigonal Planar?
I like to think of it in terms of bonds and lone pairs. Trigonal planar is AX3 while T shaped is AX3E2. The key here is that t shaped has 2 lone pairs which creates repulsion, changing the bond angle from 120 of trig planar and making it 90.

Why are not supposed to use the Ryberg equation? I find it easier.

De Neve Cedar Study Group? 14A
Hey guys! Given our quiz is next week, does anyone in de neve cedar want to get together to study? Let's figure out who can meet up this weekend for a little review session, maybe do some practice problems together.

Re: Wavelike Properties of Electromagnetic Radiation/Light
Yes I believe the extent of change refers to the concept of the electrical field corresponding to amplitude.
