### 3 Substituents

When naming organic compounds how would we determine if it is Z or E if the compound has three Substituents?

### Cyclic Formations

Would it be possible to have an organic compound that is simply two connect cyclic structures? If so, how would the parent chain be chosen? Would it all just be one chain or would you have to arbitrarily choose a side?

### Energy of Transitional States

When comparing the various states of a reaction a g value, or energy barrier, can be given in a diagram. If two transitional states were to be compared would the one with the higher g be less formed than the other?

### Food Rxns

On page 76 of our course reader, when explaining the relationship between reaction rate and temperature, it uses food in a refrigerator as an example. It says that a colder temperature preserves food by slowing down specific types of reactions. I was just wondering what sort of reactions it was refe...

### Formula Sheet

In our course reader we have covered certain equations, such as how to calculate K for redox rxns, yet they do not appear on the front of the test. For formulas like that, do we have to be able to derive them/memorize them?

### Inert Conductors as Electrodes

In our course reader it says that platinum is the most common metal to be used as an electrode. Why is this so? After doing some research online it seems unclear as to if platinum or gold is more ductile. Is this simply a cost thing or does it have something to do with the metal having to be inert?

### Drawing Diagrams

In lecture we were told that the Anode should be drawn on the left, and the cathode on the right. Is there a scientific reasoning behind this or is this simply to follow convention?

### Isolated Systems

In terms of an isolated system, are there any real world examples? I know it occurs in a lab setting, but is that the only place where it is possible?

### 8.6 First Law Clarification

On page 272 it says, "It is an experimental fact... that we cannot use a system to do work, leave it isolated for a while, and then return to it to find its internal energy restored to its original value and ready to provide the amount of work again." Is this because internal energy is a s...
