Missing information

I'm missing mentioning of other (more advanced) ways of describing chemicals, such as IUPAC nomenclature, or visual representations, as for example File:Flutamide.gif (how do you actually call these diagrams?). --Abdull 17:06, 6 December 2005 (UTC)

Those are usually called "structure diagrams". Itub 23:55, 2 January 2006 (UTC)

Ax2

  um.... i wanted to know how to a write a chemical formula for given elements correctly. i know about the ratio method but it doesnt work with non- metals and non - metals.

Question

What does a formula such as FeS_2-x mean? Can this be included in the article?

See Non-stoichiometric compound. Yes, I think it should be mentioned in the article. Itub 16:07, 9 February 2006 (UTC)

Thanks ;)

chemical compounds

Do the groups of chemical equations Ch3OCH3, Ca3(PO4)2,CO2,H2CO3 contain entirely of organic compounds?

No. DMacks 16:06, 4 May 2006 (UTC)

chemical/molecular/empirical formula

The article on Empirical Formula equates "chemical formula" with "empirical formula," and distinguishes "molecular formula"

The article on Chemical Formula equates "chemical formula" with "molecular formula" and distinguishes "empirical formula"

(There is no separate article on "Molecular Formula")

So who is right?

naming elements in formulae?

how are chemical formulae read in english? for example, water is , and what about iron - or ?

Mystery Symbol

in a number of chemicle composition formulas, I've encountered a symbol before the equation that looks like the infinity symbol with half of the second loop sliced off, or an 'o' and a 'c' pushed together. I am wondering what exactly this symbol means in reference to the equation. I've not encountered it anywhere else before.

e.g- Goethite: 'oc' - FeO(OH)

Sounds like the "proportional to" sign (∝). Maybe it's used to indicate a non-exact formula representation (correct chemical formula, but actual allotrope or mineral form not completely represented), but I'm only hypothesizing here. DMacks 02:43, 3 January 2007 (UTC)

Order

In which order are elements in the chamical formula ordered? --Artman40 12:32, 9 January 2007 (UTC)
