CaCl 2 + Na2CO3 :rarrow: CaCO3 + 2NaCl

Just a test on my message formatting

After all, that’s what this thread is for, isn’t it? I think this thread should be a sticky, but hey, I’m too knew around here to make such suggestions. Even though I’ve lurked here for a long time. Just a thought.

Good idea.

Good idea.

I thought it was at one stage, maybe things were broken on an update.

Or someone (could be me) unstickied it accidentally at some point.

Clausius–Clapeyron relation

the above was create using url rather than zrl below

Mass Relationships of Simple Compounds of Nitrogen and Oxygen

           Compound Total Mass (g) Mass of Nitrogen (g) Mass of Oxygen (g)

Oxide A     3.28                             1.00                             2.28
Oxide B     2.14                             1.00                             1.14
Oxide C     1.57                             1.00                             0.57


Possible Molecular Formulae for Nitrogen Oxides
Assuming that:

                          Oxide C is NO            Oxide B is NO              Oxide A is NO
                       
Oxide A is                 NO4                     NO2                              NO
Oxide B is                 NO2                     NO                                N2O
Oxide C is                 NO                       N2O                              N4O

The following site has a nice sandbox for testing out LaTeX code (and is a good reference as well).

http://www.forkosh.com/mimetextutorial.html
I used this all the time and the sandbox doesn't seem to be there any more. Am I the only one with this problem?

In the meantime, will use this space for some testing Tex code

[tex]C=kt \frac{L-x}{L}-\frac{kL^2}{D}\left(\frac{x}{3L}-\frac{x^2}{2L^2}+\frac{x^3}{6L^3}\right)+\frac{2kL^2}{D\pi^3}\sum_{n=1}^{\infty}\frac{1}{n^3}\sin{\left( \frac{n \pi x}{L} \right)}\exp{\left( -\frac{Dn^2 \pi^2 t}{L^2}\right)}[/tex]

[tex]C=kt \frac{L-x}{L}+k\frac{(L-x)^3}{8LD}+\frac{2kL^2}{D\pi^3}\sum_{n=1}^{\infty}\frac{1}{n^3}\sin{\left( \frac{n \pi x}{L} \right)}\exp{\left( -\frac{Dn^2 \pi^2 t}{L^2}\right)}[/tex]
