Answer: (i) Major part of all living system is made of water. (ii) It constitutes about 65 – 70% of body weights of animals and plants. (iii) Some properties of water like high specific heat, thermal conductivity, surface tension, high polarity allow water to play a major role in biosphere.
2010-09-08 · You only had 3% H2O2 in what was approximately 8 ounces of water. Rough estimation puts that around 450g water, of which 3% or 15g was H2O2. This is roughly .3 mol of H2O2, and because of the reaction, you will only get .15 mol of O2 or two liters of oxygen if all of it reacted (again, incomplete reactions) and got out of solution.

Organic peroxides are organic compounds containing the peroxide functional group (ROOR′). If the R′ is hydrogen, the compounds … 2 days ago Many substances catalyse its decomposition, like transition metals and their compounds, such as MnO 2; the enzyme catalase in the human liver does the important job of removing toxic H 2 O 2 (a byproduct of oxidation reactions) from the body. Even dust can act as a catalyst.
Alternative compounds that release chlorine and are used in the health-care setting include demand-release chlorine dioxide, sodium dichloroisocyanurate, and chloramine-T. The advantage of these compounds over the hypochlorites is that they retain chlorine longer and so exert a more prolonged bactericidal effect.

h2o is a compound of two elements for instance in this eqution it include two hydrogen molecules and one oxygen molecule.
What is wrong with this formula?
If a large fraction of the BOD and COD is contributed by inorganic reduced sulfur compounds such as sulfides, sulfides, or thiosulfate, then hydrogen peroxide alone is typically effective. Hydrogen Peroxide is (H2O2), water plus one extra atom of oxygen. When Hydrogen Peroxide come in contact with germs and bacteria, that extra atom of oxygen bonds with germs and bacteria, thus oxidizing them on contact, destroying them without any harm, or side effects. Hydrogen Peroxide (H2O2) Therapy – By Dr. David G. Williams

The added oxygen also makes hydrogen peroxide quite unstable, unless it is quite pure. ordinary combustible materials. Inorganic peroxides react with organic compounds to generate organic peroxide and hydroperoxide products and react violently with reducing agents (6). Sodium peroxide, hydrogen peroxide, sodium perborate, and sodium persulfate are present in many labs.
Since the additional oxygen atom is "electron-loving," or electrophilic, hydrogen peroxide is a very powerful oxidizing agent. The added oxygen also makes hydrogen peroxide quite unstable, unless it is quite pure.

And through catalysis, H2O2 can be converted into hydroxyl radicals (.OH) with reactivity second only to fluorine. H2O2 indeed decomposes spontaneously, that's why companies usually add stabalizers to bottles of H2O2 solutions.
