H and O combine into water H20 in chemistry So what s going on with H202 hydrogen peroxide ?

It is hydrogen peroxide. Hydrogen peroxide is an inorganic compound with the chemical formula H2O2. Pure hydrogen peroxide is a light blue viscous liquid, miscible with water in any proportion, is a strong oxidizing agent, aqueous solution is commonly known as hydrogen peroxide, is a colorless transparent liquid.

Its aqueous solution is suitable for medical wound disinfection, environmental disinfection and food disinfection.

Hydrogen peroxide laboratory method:In 100ml of 15-18% sulfuric acid, under the cooling of ice, gradually add barium peroxide, and the amount added is to maintain the weak acidity of the solution (about 40g). The hydrogen peroxide solution is obtained by pouring the upper solution.

Extraction can be carried out if necessary. Extract 4-5 times with 20ml each time. Evaporate the ether extract on a water bath (not higher than 40) to remove the ether and move the remainder to a dry sulfate bottle.

50% hydrogen peroxide solution can be prepared by this method.

Uses of H2O2:In different cases, there can be oxidation or reduction. Oxidants, bleach, disinfectants, dechlorinators, rocket fuel, organic or inorganic peroxides, foams and other porous substances can be used.

Answer: Analysis:

A small amount of manganese dioxide is put into the mu respectively, and if the mu of worms is released, the gas that can rekindle the Martian wood strips is quickly buried, and it is double blind oxygen water (H2O2).

It's hydrogen peroxide.

Also called: hydrogen peroxide.

Hydrogen peroxide, the chemical formula is H2O2, pure hydrogen peroxide is a light blue viscous liquid, which can be mixed with water in any proportion, is a strong oxidizing agent, and the aqueous solution is commonly known as hydrogen peroxide, which is a colorless transparent liquid. Its aqueous solution is suitable for medical wound disinfection, environmental disinfection and food disinfection. In general, it will decompose into water and oxygen, but the decomposition rate is extremely slow, and the way to speed up the reaction is to add a catalyst - manganese dioxide or irradiate it with short-wave rays.

Pure hydrogen peroxide is a light blue viscous liquid with a melting point of °C and a boiling point of °C, and the molecular configuration of pure hydrogen peroxide will change, so the melting and boiling point will also change. The density of the solid at the freezing point is and the density decreases with increasing temperature. It has a greater degree of association than H2O, so its dielectric constant and boiling point are higher than water.

Pure hydrogen peroxide is relatively stable, and when heated to 153 °C, it violently decomposes into water and oxygen, and it is worth noting that there are no intermolecular hydrogen bonds in hydrogen peroxide.

Hydrogen peroxide has a strong oxidizing effect on organic matter and is generally used as an oxidizing agent.

It is called hydrogen peroxide in chemistry.

Answer: Because the number of outermost electrons of the hydrogen atom is only 1, it is possible to lose only 1 electron; The number of electrons in the outermost shell of the oxygen atom is 6, so that 2 electric sliders can be obtained. Therefore, an oxygen atom must obtain two electrons from two hydrogen atoms, so it becomes a water molecule H2O

Hydrogen peroxide (H2O2) has the same elemental composition as water (H2O): both are composed of hydrogen and oxygen.

However, their molecular composition is different: each H2O2 molecule is composed of two hydrogen atoms and two oxygen atoms, while each H2O molecule is composed of two hydrogen atoms and one oxygen atom.

The molecular makeup of the two is different, so their chemical properties are different.

Hydrogen peroxide (H2O2) is a compound with the molecular formula H2O2 that is composed of the elements hydrogen and oxygen. Its structure contains a chemical bond of an oxygen atom and a hydrogen atom.

From the perspective of hybridization theory, the bond between the oxygen atom and the hydrogen atom of hydrogen oxide belongs to sp hybridization. This is because the electronic configuration of the oxygen atom is 1s 2s 2p and is able to form two sigma bonds, and the hole slip requires one sp hybrid orbital for each sigma bond. With sp hybridization, one 2S orbital and two 2P orbitals of the oxygen atom are mixed to form three sp hybrid orbitals, which overlap with the 1S orbital of the hydrogen atom to form a sigma bond.

Thus, the chemical bond between the oxygen atom and the hydrogen atom of hydrogen peroxide is sp hybridized.

This hybrid form gives the hydrogen peroxide molecule high stability and activity. It acts as a strong oxidizing agent and plays an important role in many chemical and biochemical reactions. At the same time, hydrogen peroxide is an important disinfectant and bleaching agent and is used in a variety of applications in the medical, hygiene, industrial and environmental sectors.
