The molecular formula of sulphur is ${\mathrm{S}}_8$ in which eight sulphur atoms are bonded to each other to form one ring. Draw an electron-dot structure for ${\mathrm{S}}_8$.

Hydrogen peroxide decomposes on its own by the following reaction.

$4\mathrm{H}-\mathrm{O}-\mathrm{O}-\mathrm{H}\to 2\mathrm{H}-\mathrm{O}-\mathrm{H}+{\mathrm{O}}_2$

From this, what will be your inference about the strength of $\mathrm{O}-\mathrm{O}$ covalent bond?

Hydrogen peroxide decomposes on its own by the following reaction.
