chemical reaction

$H_2O = H^+ + OH^-$

$2Al + 2OH^- + 2H_2O = 2AlO2^- + 3H_2\uparrow$

$Cl_2 + H_2O = H^+ + Cl^- + HClO$

$Ca^{2+} + CO3^{2-} = CaCO3 \downarrow$

$1 \ge 2$ is false

$a^2 + b^2 \ge 2ab$

$\lim_{x \to 0} \frac{sin(x)}{x}$

$\frac{\partial z}{\partial x}$

$\frac{dy}{dz}$

$\sum\limits_{i = 1}^n{i^2} = \frac{n(n+1)(2n+1)}6$
