=====Chem plugin=====
This DokuWiki plugin formats a molecular formula by using ‘chem’ tag.

**C<sub>2</sub>H<sub>5</sub>O<sub>2</sub><sup>-</sup>Na<sup>+</sup>**

Without this plugin, you have to write a code for chemical expression with lengthy and messy code like this.
<code>
C<sub>2</sub>H<sub>5</sub>O<sub>2</sub><sup>-</sup>Na<sup>+</sup>

</code>

The chem plugin will help you with shorter expression like this.
<code>
<chem>C2H5O2-Na+</chem>

</code>


====Examples====
C<sub>2</sub>H<sub>6</sub>
<code><chem>C2H6</chem></code>

Na<sub>2</sub>HPO<sub>4</sub> 12H<sub>2</sub>O
<code><chem>Na2HPO4 12H2O</chem></code>

C<sub>2</sub>H<sub>5</sub>O<sub>2</sub><sup>-</sup>Na<sup>+</sup> 
<code><chem>C2H5O2|-Na+</chem>    // | is a splitter.</code>

Cl<sub>2</sub>H<sub>6</sub>N<sub>2</sub>Pt<sup>2+</sup> 
<code><chem>Cl2H6N2Pt2+</chem></code>

Al<sub>2</sub>(SO<sub>4</sub>)<sub>3</sub>
<code><chem>Al2(SO4)3</chem></code>
