## Chemical LaTeX typeset

If you mean how to use it outside of PF, you need to download a program such as miktex (www.miktex.org).
 Blog Entries: 9 Recognitions: Homework Help Science Advisor Thanks for the link,Sirus.Maybe i'll get read of the old Scientific Workplace that i'm using now.
 For small applications, you can preview a post on PF with the required code in it, then copy and paste the latex into MS Word or another word processing application. This is discouraged, however, to avoid excess traffic on the PF server (copy/pasting Latex is not, after all, the purpose of PF).
 Recognitions: Homework Help Science Advisor Trying it out, $$H^+ _{(aq)} + OH^- _{(aq)} \xrightarrow~H_2 O _{(l)}$$
 Recognitions: Homework Help Science Advisor I should be studying, $$1/p + 1/q = 1/f$$
 Recognitions: Homework Help Science Advisor this is killing me $${\Delta G} = {\Delta G^_o} - RT\textit{lnQ}$$ from my current physics course lens maker's equation $$\frac{n_1}{p} + \frac{n_2}{q} = (n_1-1) \left[ \frac{1}{R_1} - \frac{1}{R_2} \right]$$ I'll just do my hw here $$\int ( \textit{lnt} )^2 dt$$ $$u= ( \textit{lnt} )^2$$ $$du=2( \textit{lnt} )( \frac{1}{t} )$$ $$dv= dt$$ $$v= \int dt = t$$ $$\int ( \textit{lnt} )^2 dt = ( \textit{lnt} )^2t - \int 2t( \textit{lnt} )( \frac{1}{t} )$$
 Recognitions: Gold Member Science Advisor Staff Emeritus Anyone (ambitwistor ?) know the symbol for the equilibrium (upper half of right arrow above lower half of left arrow) sign ?
 Recognitions: Homework Help Science Advisor just trying things out $$\xrightarrow{\leftarrow}$$ I noticed Monique's first post where she had the n,n over the arrow and figured one could go on from there. $$\xrightarrow{\xleftarrow}$$
 Recognitions: Gold Member Science Advisor Staff Emeritus Clever ! That'll have to do until I think it's important to hunt this down or someone comes up with a better answer.
 Recognitions: Gold Member Science Advisor If you have already found this, forgive me, but the solution is \rightleftharpoons or \leftrightharpoons as in the following examples: $$H_2O \rightleftharpoons H^+ + OH^-$$ $$H_2O \leftrightharpoons H^+ + OH^-$$

 Quote by Another God that \ thing never does what I want...$6CO_2 + 6H_2O \xrightarrow{Light\Energy} C_6 H_{12} O_6 + CO_2 ~\Delta \ \ \ \G^{\circ} = +2870kJ/mol$ Maybe I should use that comma? $6CO_2 + 6H_2O \xrightarrow{Light/,Energy} C_6 H_{12} O_6 + CO_2 ~\Delta /, /, /, G^{\circ} = +2870kJ/mol$ $6CO_2 + 6H_2O \xrightarrow{Light\,Energy} C_6 H_{12} O_6 + CO_2 ~\Delta \, \, \, G^{\circ} = +2870kJ/mol$ I think i prefer the tilde (~) key...$6CO_2 + 6H_2O \xrightarrow{Light~Energy} C_6 H_{12} O_6 + CO_2 ~\Delta~~~G^{\circ} = +2870kJ/mol$
lol guys, the photosynthesis equation everyone's using is incorrect ;)
 $$F = \frac {1}{4\pi\epsilon_0}\frac{Q_1Q_2}{r^2}$$ $$E_p = \frac {Q_1Q_2}{4\pi\epsilon_0(r_1+r_2)}$$ $$E_p = \frac {e^2}{4\pi\epsilon_0(2r_0)}$$ $$Q = EV \\$$ $$Q = eV \\$$ $$E_p = \frac {e}{4\pi\epsilon_0(2r_0)} electron volts$$ $$E_k = \frac{3}{2}kT$$ $$\gamma \equiv \frac{1}{\sqrt{1 - v^2/c^2}}$$
 Does anybody know the fancy "capital E" symbol denoting reduction potentials? I mean, it doesn't seem to be in LaTex---or is it? Where can I get it? Edit: Is it by any chance a lowercase "xi" ? That is, a $$\xi ^\circ$$ ??
 Recognitions: Homework Help Science Advisor are you referring to emf?
 Yes!! What is the symbol for it? (the fancy capital E thing)!!?? Is it on LaTex??
 Recognitions: Homework Help Science Advisor I've seen it here somewhere. You may want to somehow italicize the E within the latex. just trying things out... $$\varepsilon$$
