<h1>Chemical Reaction Editor</h1>
<h3>Description</h3>
<ul>
<li>Reactants are separated from products by '->'.</li>
<li>Individual reactants and products are separated by '&nbsp;&nbsp;+' (leading space is obligatory).</li>
<li>Numbers preceding the first symbol of a chemical specie are considered to be stoichiometric coefficients.</li>
<li>Numbers appearing after the first symbol of a chemical specie are considered to be subscripts.</li>
<li>Superscripts are initialized by '^' and terminated by a space.</li>
<li>Ionic charges are superscripts composed of a number followed by a sign (i.e. '^2+').</li>
</ul>

<h3>Examples</h3>
<ul>
<li>Ca(NO<sub>3</sub>)<sub>2</sub> is written as:<br>&nbsp;&nbsp;&nbsp; Ca(NO3)2</li>
<li>OH<sup>-</sup> + H<sub>3</sub>O<sup>+</sup> <m>$\rightarrow$</m> 2H<sub>2</sub>O is written as:<br>&nbsp;&nbsp;&nbsp; OH^- + H3O^+ -> 2H2O</li>
<li>[Co(H<sub>2</sub>O)<sub>6</sub>]<sup>2+</sup> + 4Cl<sup>-</sup>  <m>$\rightarrow$</m> [CoCl<sub>4</sub>]<sup>2-</sup> + 6H<sub>2</sub>O is written as:<br>&nbsp;&nbsp;&nbsp; [Co(H2O)6]^2+ + 4Cl^- -> [CoCl4]^2- + 6H2O</li>
<li><sup>3</sup><sub>1</sub>H + <sup>2</sup><sub>1</sub>H  <m>$\rightarrow$</m> <sup>4</sup><sub>2</sub>He + <sup>1</sup><sub>0</sub>n is written as:<br>&nbsp;&nbsp;&nbsp; ^3 1H + ^2 1H -> ^4 2He + ^1 0n</li>
