用 $\LaTeX$ 高效排版化学方程

$$\ce{H2O}$$

$$\ce{Ca(OH)2 + CO2 = CaCO3 v + H2O}$$

$$\ce{2KClO3} \xlongequal[\Delta]{\ce{MnO2}} \ce{2KCl + 3O2 ^}$$

$$\mathrm{e}[(\mathrm{e}+\pi)(\mathrm{e}+\pi+\mathrm{e})]^\mathrm{e}+\dfrac{\mathrm{e}}{(\pi^\mathrm{e}-\mathrm{e})(\mathrm{e}-\pi^\mathrm{e}+\mathrm{e}^\pi)} \approx 114514.1919810$$
