$\left(\mathrm{a}\right)$ Decomposition of hydrogen peroxide gives di-oxygen.
$\left(\mathrm{b}\right)$ Like hydrogen peroxide, compounds, such as $\mathrm{K}\mathrm{C}\mathrm{l}{\mathrm{O}}_3,\mathrm{P}\mathrm{b}\left(\mathrm{N}{\mathrm{O}}_3\right)$ and ${\mathrm{N}\mathrm{a}\mathrm{N}\mathrm{O}}_3$ When heated liberate di-oxygen.
$\left(\mathrm{c}\right)$ $2$-Ethylanthraquinone is useful for the industrial preparation of hydrogen peroxide.
