Did I miss any

SMILES at Daylight site
http://www.daylight.com/dayhtml/doc/theory/theory.smiles.html
SMILES at wikipedia
http://en.wikipedia.org/wiki/SMILES
ChemSketch
http://www.acdlabs.com/download/
LaTeX
http://en.wikibooks.org/wiki/LaTeX/Mathematics)

I believe it is a good starting collection, at least for the forum. There is much more to LaTeX, but most of it is of no use for us.

Just smiles testing some ketones

CC(C)=O

O=C(C)CC or CCC(=O)C

O=C(C)CCC
CC(C)C(=O)C
O=C(CC)CC

Just smiles testing some acids

O=CO

CC(O)=O

CCC(=O)O

O=C(O)CCC or CCCC(=O)O

CCCCC(O)=O

Just playing with tex

[tex] \frac {(2)}{(4)} = \frac {(1)}{(2)} [/tex]

[tex] \frac {(P_1 . V_1)}{(n_1 . T_1)} = \frac {(P_2 . V_2)}{(n_2 . T_2)} [/tex]

Zn(s) + 2 HCl(ac) :rarrow: H2 (g) + ZnCl2 (ac)

Zn+2(ac) + Y-4(ac)  :rarrow: [ZnY]-2(ac)

nZn+2=nY-4= 0.0011 mol

Don't mind me. Just me failing at making divisions in tex.
Yes, I wrote states as subscripts. That's the way it's done around here.

There is no such thing as "here" here.

IUPAC rules are clear and they are defined to be used by everyone.

Yes the rules are clear but how does one mandate everyone to use them? :)

Technically you don't, but it is a matter of being clear and unambiguous. What is VO2+? IUPAC rules tell you how to write it in an unambiguous way, why not stick to them?

I have yet to peruse the IUPAC rules

(ac) comes from "acuoso", aqueous in Spanish. I used it all over my Olympiad exams, without any penalization, because the entire exam was in Spanish.

Those zinc equations were for an assignment. In Spanish again.

I was taught to use (ac), as you can see. This is what every future Olympic will be taught, so I'll try to show this discrepancy, and an example of what happens when they use (ac) instead of (aq). I'll use (aq) as long as I don't forget when posting here, also.

Some more practice

Cobalt(II) oxide
WIKI
[Co]=O
SPIDER
[O-2].[Co+2]

Cobalt(III) oxide
SPIDER
O=[Co]O[Co]=O

Cobalt(II,III) oxide
WIKI
[Co]=O.O=[Co]O[Co]=O
SPIDER
[Co+2].[Co+2].[Co+2].[O-2].[O-2].[O-2].[O-2]

Cobalt(II) carbonate
SPIDER
C(=O)([O-])[O-].[Co+2]

testing

Glycerol or Glycerin C3H8O3
WIKI
C(C(CO)O)O
SPIDER
C(C(CO)O)O

Strange. Why C(C(CO)O)O when OCC(O)CO is much simpler? Perhaps wiki has some computer generated code.
