finding acceptable double arrows for chemical equations

$Fe{\left( {OH} \right)_3} \Leftrightarrow F{e^{3 + }} + 3{\left( {OH} \right)^ - }$

$Fe{\left( {OH} \right)_3} \leftrightarrow F{e^{3 + }} + 3{\left( {OH} \right)^ - }$

$Fe{\left( {OH} \right)_3} \mathbin{\lower.3ex\hbox{\buildrel\textstyle\rightarrow\over {\smash{\leftarrow}\vphantom{_{\vbox to.5ex{\vss}}}}}} F{e^{3 + }} + 3{\left( {OH} \right)^ - }$

Testing some inline maths like $$d^{3n}xd^{3n}p\rho\left(x,p\right)$$, $$y = x^2$$ or $$\varepsilon_{\alpha\beta\gamma}\varepsilon_{\alpha\mu\nu}=\delta_{\beta\mu}\delta_{\gamma\nu}-\delta_{\beta\nu}\delta_{\gamma\mu}$$ should work.

Trying to post a Cayley table

$\begin{array}{*{20}{c}} + & 0 & 1 \\ 0 & 0 & 1 \\ 1 & 1 & 1 \\ \end{array}$

$\begin{array} + & 0 & 1 \\ 0 & 0 & 1 \\ 1 & 1 & 1 \\ \end{array}$

$\begin{array}{*{20}{c}} + & 0 & 1 \\ 0 & 0 & 1 \\ 1 & 1 & 1 \\ \end{array}$

what does MathML mean? is this libreoffice's one pocket usage (i.e. program like libre office writer)

It's a mark-up language; a subset of XML: https://www.w3.org/Math/whatIsMathML.html

Sorry what I posted was inline LateX, but you can read it as MathML by right-clicking.
