Hydrogen peroxide is made up of hydrogen atoms and oxygen atoms How wrong 20

According to hydrogen peroxide.

The chemical formula (H2O2) shows that hydrogen peroxide is made up of the element hydrogen.

and the element of oxygen, or it can be said that a hydrogen peroxide molecule is made up of two hydrogen atoms and two oxygen atoms, so it cannot be said that hydrogen oxide is composed of hydrogen atoms and oxygen atoms.

Hydrogen peroxide physical properties:

The aqueous solution is a colorless and transparent liquid, soluble in water, alcohol and ether, insoluble in benzene and petroleum ether.

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. Its degree of association is greater than that of H2O, so its dielectric constant.

and the boiling point is higher than that of water. Pure hydrogen peroxide is relatively stable and violently decomposes into water and oxygen when heated to 153 °C.

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

Hydrogen Peroxide Chemistry:

1. Oxidation.

Pure hydrogen peroxide.

Lead white [basic lead carbonate] in oil painting will be mixed with hydrogen sulfide in the air.

The reaction produces black lead sulfide, which can be washed with hydrogen peroxide).

2. Reducibility.

3. In 10ml of 10% sample solution, add 5ml of dilute sulfuric acid test solution (TS-241) and potassium permanganate.

Test solution (TS-193) 1ml. Bubbles should occur, and the purplish-red color of potassium permanganate disappears. to litmus.

It is acidic. It is explosive in case of organic matter.

4. Take 1g of sample (accurate, dilute with water. take 25ml of this solution, add 10ml of dilute sulfuric acid test solution (TS-241) and titrate with potassium permanganate. per milliliter. Potassium permanganate is equivalent to hydrogen peroxide (H2O2).

5. Oxygen and water are liberated by organic matter and heat, and react violently with chromic acid, potassium permanganate, metal and carbonic acid. To prevent decomposition, trace amounts of stabilizers such as sodium stannate and sodium pyrophosphate can be added.

Wait a minute. 6. Hydrogen peroxide is an extremely weak acid: H2O2 = (reversible) = H++Ho2- (Ka=. Therefore, the peroxide of the metal can be regarded as its salt.

It is supposed to be made of hydrogen peroxide molecules, which are made up of hydrogen atoms and oxygen atoms.

It is constructed by hydrogen peroxide molecules, which are made up of the one you said.

Hydrogen is the right thing to do with oxygen.

The molecular composition of hydrogen peroxide (H2O2) consists of 2 hydrogen atoms and 2 oxygen atoms. It is formed by the combination of one oxygen atom and one hydrogen atom in two water molecules (H2O), which can be seen as a variation of the water molecule. Hydrogen peroxide, with the chemical formula H2O2 and molecular weight g mol, is a stable and highly rotten fiber active compound that usually exists as a solution at a concentration of 30%.

Hydrides are binary compounds formed by hydrogen with other elements. However, in general scientific and technological work, the binary compound of hydrogen and metal is always called hydride, and the binary compound of hydrogen and non-metal is called a certain hydrogen. In the periodic table, almost all elements except noble gases can form hydrides with hydrogen, which are roughly divided into three categories: ionic, covalent and transitional, and their properties are different.

There are only two types of hydride of oxygen: water and hydrogen peroxide!

No, water is hydrogen oxide, it is an oxide of hydrogen, hydrogen peroxide is a peroxide of hydrogen, and hydrogen superoxide is a superoxide of hydrogen.

At present, there is no hydride of oxygen, only the perhydride of oxygen, i.e., oxygen perhydrogenated - hoohh2s is the sulfide of hydrogen.

Hydrides are compounds that are combined with hydrogenation.

The hydrides of oxygen are water and hydrogen peroxide. For example, S, is H2S.

The chemical equation for the reaction of hydrogen and oxygen is sold.

and redox equilibrium.

Due to the oxygen manifest -1 valence in hydrogen peroxide, the electronic formula of hydrogen peroxide h:[o::o]2:

h The two oxygen are combined to form a co-2 valence as a whole, while one of the oxygen -2 valence in N oxide a is independent of oxygen, so it can only be read as hydrogen peroxide.

Molecular formula: H2O2 .

Molecular weight:. Melting Point: -89.

Boiling point:. Refractive index:.

Properties: colorless heavy liquid.

Solubility: Can be mixed with water, ethanol or ether in any proportion.

Uses: In different cases, there can be oxidation or reduction. It can be used as an oxidizing agent, bleaching agent, disinfectant, dechlorinator, and for rocket fuel, organic or inorganic peroxide, foam and other porous substances.

Preparation or**: It can be prepared by sulfuric acid acting on barium peroxide, or electrolytic oxidation of sulfuric acid into persulfuric acid or sulfate into persulfate and then hydrolysis, or by hydrogenation and oxidation of 2-ethylanthraquinone.

Note: Commercially available products are generally 30% or 3% aqueous solution. It is decomposed into water and oxygen during storage. A small amount of N-acetanilide, N-acetoethoxyaniline and other stabilizers can be added.

Catalog:Peroxide.

The solution of hydrogen peroxide contains hydrogen ions and peroxide ions, and peroxide will generate hydroxide ions under the action of hydrogen ions, in which the concentration of hydrogen ions is greater than the concentration of hydroxide ions, so hydrogen peroxide is acidic. Hydrogen peroxide is slowly decomposed into water and oxygen at room temperature, and the oxygen produced by decomposition is not originally present in hydrogen peroxide, but undergoes chemical changes to produce a new substance, oxygen ......

It cannot be said that hydrogen oxide contains oxygen molecules, but that a chemical change has taken place to produce oxygen molecules that did not exist in the first place, but it can only be said that hydrogen oxide contains oxygen elements, and oxygen elements (macroscopic balances) and oxygen molecules (microscopic) are not the same concept.

Because of the peroxide structure contained in hydrogen peroxide, it can only be read as hydrogen peroxide.

Pure hydrogen peroxide is a light blue viscous liquid, which can be miscible with water in any proportion, and is a strong oxidizing agent.

In general, it will slowly decompose into water and oxygen, but the decomposition rate is extremely slow, and the way to speed up the reaction is to add catalysts such as manganese dioxide or irradiate it with short-wave rays.

Pure water can conduct electricity, but it is a very weak electrolyte in the ten wide segments. Water in daily life has more anions and cations due to the dissolution of other electrolytes, and has more obvious electrical conductivity.
