Chemical equations

One can show chemical symbols and equations as shown in this list of examples. Here are a few examples:

$\mathrm{C}\mathrm{O}{\phantom{A}}_2+\mathrm{C}⟶2\mathrm{C}\mathrm{O}$

$\mathrm{H}\mathrm{g}{\phantom{A}}^{2+}\stackrel{\mathrm{I}{\phantom{A}}^{-}}{\to }\mathrm{H}\mathrm{g}\mathrm{I}{\phantom{A}}_2\stackrel{\mathrm{I}{\phantom{A}}^{-}}{\to }[\mathrm{H}\mathrm{g}{\phantom{A}}^{\mathrm{I}\mathrm{I}}\mathrm{I}{\phantom{A}}_4]{\phantom{A}}^{2-}$

$\mathrm{H}{\phantom{A}}_2\mathrm{O}$

$\mathrm{Y}{\phantom{A}}^{99+}$

${\phantom{A}}_{\phantom{90}}^{\phantom{227}}{\phantom{A}}_{\phantom{2}90}^{\phantom{2}227}\mathrm{T}\mathrm{h}{\phantom{A}}^{+}$

$\mathrm{A}\stackrel{-\rightharpoonup }{\leftharpoondown }\mathrm{B}$

which were programmed as:

<chem>CO2 + C -> 2 CO</chem>
<chem>Hg^2+ ->[I-] HgI2 ->[I-] [Hg^{II}I4]^2-</chem>
<chem>H2O</chem>
<chem>Y^99+</chem>
<chem>^{227}_{90}Th+</chem>
<chem>A <=>> B</chem>

Cross references

You can reference a block of chemical symbols using CrossReference method. Here is a sentence that references an equation "1":

This example uses <xr id="eqn:In1"/> that illustrates formulas.

<equation id="eqn:In1" shownumber>

$\mathrm{H}\mathrm{g}{\phantom{A}}^{2+}\stackrel{\mathrm{I}{\phantom{A}}^{-}}{\to }\mathrm{H}\mathrm{g}\mathrm{I}{\phantom{A}}_2\stackrel{\mathrm{I}{\phantom{A}}^{-}}{\to }[\mathrm{H}\mathrm{g}{\phantom{A}}^{\mathrm{I}\mathrm{I}}\mathrm{I}{\phantom{A}}_4]{\phantom{A}}^{2-}$ </equation>

The WikiCode that was used in this example is:

This example uses <xr id="eqn:In1"/> that illustrates complex blocks of equations. 

:<equation id="eqn:In1" shownumber>
<chem>
Hg^2+ ->[I-] HgI2 ->[I-] [Hg^{II}I4]^2-
</chem>
</equation>

Note that <xr id="eqn:In1"/> is "clickable" so you can always navigate to the equation you are referencing to.
