The ⇋ symbol, officially known as the Leftwards Harpoon Over Rightwards Harpoon, features two stacked half-arrows pointing in opposite directions. In chemistry, it serves as a specialized equilibrium arrow to denote a reversible reaction, often emphasizing the reverse process. You'll frequently encounter it in scientific typesetting and academic texts to illustrate dynamic two-way systems.
How to Type

In Programming
In LaTeX and scientific programming, this symbol is generated using `\leftrightharpoons` to typeset chemical equations or logical bidirectionality. It is primarily used to render academic formulas representing dynamic equilibrium rather than functioning as a logical operator in source code.
