This article has used different markup styles:

2H₂ + O₂ --> 2H₂O

2H₂ + O₂ --> 2H₂O

Both styles are typographically inadequate. I tried to fix the right arrow with → with the following result:

2H₂ + O₂ → H₂O

which isn't rendered quite right in my browser (IE 6.0)—the arrow is on the baseline instead of "hyphen height". (The problem seems to be that the arrow is centered vertically on the whole line, which is pulled down by the subscripts. For example, H→O does look right.) Finally, I have decided to switch to TeX markup

$2\,\mbox{H}_2+\mbox{O}_2\to2\,\mbox{H}_2\mbox{O}$

in the hope that this satisfies everybody.

I love how the formula for thermite is on this page. Mayhaps an explosive should not be used as an example. miles32

It is explosive. :) Other reactions common in textbooks, such as H2 + O2 -> H2O are more likely to be explosive. Itub 02:27, 16 January 2007 (UTC)

Should there be H2 + O2 -> H2O + O2 Giving the other product O2?

[edit] Merger proposal

All these articles (Stoichiometry,Stoichiometric coefficient,Gas stoichiometry)are related to the same concept and would be better if they are accessible on a single page. It will help by providing a better understanding of the article and save some trouble for a person new to the concept. Myth (Talk) 21:00, 28 January 2007 (UTC)

I Believe that the links included in the See Also section should be enough... both subjects are prone to grow up enough to keep their own pages... —Preceding unsigned comment added by Paulo.maia (talk • contribs) 06:57, 26 March 2007

they should go together. 'nuff said. —Preceding unsigned comment added by 67.84.0.201 (talk)

They should be merged until it is true that they have grown and developed enough information to merit their own space in separate articles. --Antonio.sierra 01:32, 6 September 2007 (UTC)

Added a short section on the stoichiometry matrix. --hsauro 08 Oct 2007

[edit] Counting

I might just suck at counting, but I believe in "Different stoichiometries in competing reactions" there is an extra Hydrogen. Well actually it's an extra n hydrogens, but I think people get it... WAIT!!! that does say 6-n... hm... LIMEY 07:09, 2 December 2007 (UTC)

[edit] Addition

This article needs to mention something about Job's method. —Preceding unsigned comment added by 204.8.12.66 (talk) 15:16, 9 January 2008 (UTC)

In the section Stoichiometric Air/Fuel Ratios of Common Fuels, the mass percent numbers have been calculated incorrectly. For example, for ethanol, the mass ratio is given as 9 to 1 and the mass percent as .11111 which is 1/9. The total mass for this case should be 9+1=10, and then the percent fuel is 1/10 = 10%. This error is consistent for all the fuels. Jpittot (talk) 20:21, 30 January 2008 (UTC)
