Multiple Double Bonds

If an ankene has more than one double bond do you name it ____________-2,5-ene? or do you put the numbers somewhere else?

Types of names

With regards to the two types of naming we learned in class, will we be asked to use one specific form when asked to name organic compounds or will we be able to choose the one we prefer.

No charge or lone pairs

If a molecule does not have any lone pairs or charge is it automatically a nucleophile or can it still be an electrophile?

Concentration Cells Useful?

Are concentration cells actually utilized much in the real world? They seem to have little no advantage over normal galvanic cells in terms of producing energy.

Change in V AND T

If a problem involves both a change in temperature and in volume do I just break the problem into 2 parts and add them together? Or is there another way to do it, like a master equation?

Phase Change and Entropy

Whenever something changes from solid to liquid or liquid to gas it is going up in entropy correct? There are no cases in which this is false?

Mathematical Differences between open/closed

For open, closed, and isolated thermodynamic systems different equations are to be used for calculations, right? The same equations do not apply to all systems.

Sublimation in Action

CO2 seems to be the primary example of sublimation that we are all familiar with. However, I was wondering are there any other examples of sublimation or is it too uncommon that there are few examples?

Are the ions created by the loss oh a proton by an acid ALWAYS bases (and vice versa) or are there exceptions?

K value concentration vs pressure

I understand how to do the equilibrium constant questions with just one, but when the problem asks me to find the equilibrium concentration of a compound THEN give the partial pressure i am unsure of how to make that conversion.

Important Metals for Biology [ENDORSED]

Are there more notable metals that work in the human body in coordination compounds that we should be familiar with or are the 4 functions and corresponding metals in our reader all that we must know?

Memorization or Logic?

Is it better to try to memorize the whole list of names for different parts of these compounds that is in our reader or to just understand the root like CHLOR will be a form of chlorine and IOD will be iodine. Also, is it worth putting effort in learning the IUPAC names?

Is oxygen the most common element to form double bonds to optimize formal charge? it seems like it almost always does in the examples. I'm never sure if it's right to or not but it seems to always be.

Lewis Structures with Resonance

When drawing a Lewis structure for a molecule that involves resonance we do not have to draw all of the possible structures right? We just have to draw one of them because they are all correct. (I'm asking because in my chem class in high school we had to draw all of them to show that resonance was ...

Quantum Numbers

I believe that I fully understand the first and second quantum numbers, but the third one confuses me. The magnetic quantum number just identifies the orientation of the orbital (like X,y, and z) but there is no universal key to which is -1,0, or 1 right? And can the number be anything besides those...

This is specifically from problem 1.9 in the book. I did all the math correctly and have the energy numbers but I ranked them in the wrong order of how much radiation is given from each event. I do not understand how reading involves more radiation than making popcorn in a microwave oven. Is it assu...
