Why does hydrogen peroxide bubble?

The hydrogen peroxide (H2O2), has an oxygen atom more than the water. Due to this additional oxygen atom, the substance becomes very unstable and if exposed to air, that atom is easily released.

For this reason, bottles containing hydrogen peroxide must be kept tightly closed. On the other hand, the chemical reaction of hydrogen peroxide with the blood and plasma exposed in a wound, is due to the release of the excess oxygen atom. And it is this reaction of liberation of the atom that causes the liquid to bubble - only ordinary water is left. Hydrogen peroxide is used for asepsis (cleaning) of wounds because, in the process, it eliminates 60% of the bacteria that could cause inflammation in the area.
