Hydrogen peroxide to oxygen is not separated from the reaction. You just have to remember all redox reactions.
None of them are ionic reactions because ionic reactions are valency.
Unchanging reactions. And the reason why this reaction is carried out in solution is because of hydrogen peroxide.
Store only in liquid state at room temperature. To be precise, the reaction is not an ionic reaction, but now some rolls are not rigorous, and can only be replaced by chemical equations.
Now you can see why the ionic reaction is the same as the chemical equation.
-
All redox reactions are not ionic reactions.
That's true.
Compare absolutely two completely different concepts of reaction, and the cross-relationship is correct.
Hydrogen peroxide to oxygen is indeed not an ionic reaction, it is a redox reaction, and hydrogen peroxide is in water.
It is weakly acidic and ionic, but this reaction has nothing to do with ions, even hydrogen peroxide molecules will be decomposed by heat to produce water and oxygen. About ionic reactions.
Concepts you should know while equations.
Written in ionic form.
It is also easy to mislead people that it is inaccurate to write the equation like that.
-
It is not an ionic reaction, it is a redox reaction.
o2) minus 2 valence (not oxygen) becomes oxygen and oxygen in water.
The answer on the first floor is one-sided, redox reactions can all be ionic reactions.
For example, CuSo3 + Cl2 = CuSo4 + CuCl2 (untrimmed) and so on.
-
A redox reaction occurs.
Divalent iron ions are oxidized.
The price increase generates ferric ions.
The negative monovalent oxygen in hydrogen peroxide in hydrogen peroxide is reduced to produce negative bivalent oxygen in the form of water.
According to the principle that there is a rise and there is a fall, it is impossible to produce oxygen.

The chemical equation for hydrogen peroxide to produce oxygen is: 2HO (MNO catalyst) 2HO+O.
Hydrogen peroxide: the chemical formula is HO, its water-soluble and noisy solution is commonly known as hydrogen peroxide, the appearance is a colorless transparent liquid, is a strong oxidizing agent. Hydrogen peroxide can decompose at room temperature to produce oxygen and water, which decompose slowly.
Chemical properties of hydrogen peroxide:
1. Oxidation: Hydrogen peroxide has strong oxidizing property and is a very strong oxygen clumping agent.
2. Reducibility: It reacts with strong oxidants such as chlorine and potassium permanganate to be oxidized to produce oxygen.
3. In case of organic matter, oxygen and water are liberated by heating, and the reaction per mu is violent in case of chromic acid, potassium permanganate, metal and carbonic acid. In order to prevent decomposition, trace amounts of stabilizers such as sodium stannate, sodium pyrophosphate, and so on can be added.

Experimental principle of hydrogen peroxide to produce oxygen rock: hydrogen peroxide (H2O2) - water (H2O) + oxygen (O2).
Specific steps for hydrogen peroxide to produce oxygen:
Connecting devices. Check the airtightness of the device.
Then fill the Erlenmeyer flask with manganese dioxide.
Pour in hydrogen peroxide solution.
Collect oxygen. Precautions for hydrogen peroxide to produce oxygen:
The separating funnel can be replaced with a long-neck funnel, but its lower end should extend below the liquid surface to prevent the generated gas from escaping from the long-necked funnel;
The catheter only needs to be slightly inserted into the tube plug.
Air tightness check: close with a water stop clip, open the piston of the separating funnel, add water to the funnel, and the water level does not continue to fall, indicating that the air tightness is good.
When filling medicines, fill solids first and then liquids.
The advantages of this device: the start and end of the reaction can be controlled, and the liquid air jujube combustor can be added at any time.
Summary of hydrogen peroxide to oxygen:
If the solid (or solid + solid) is heated to generate gas, the potassium permanganate oxygen production device is selected;
If the gas is produced at room temperature of solid + liquid, hydrogen peroxide is used to produce oxygen.
Catalyst: A substance that can change the reaction rate of other substances in a chemical reaction, but its chemical properties and mass have not changed before and after the reaction.
The long-necked funnel is filled with hydrogen peroxide, and the lower end of the long-necked funnel should be sealed, that is, submerged in the water of the Erlenmeyer flask, and the Erlenmeyer flask is filled with manganese dioxide and water.
When charging, it is first filled with solid and then liquid.
When the air bubbles in the gas collector cylinder overflow, it means that the oxygen in the gas collector cylinder has been collected.

The same reaction as the hydroperoxide decomposition to produce oxygen and dissipate limb qi is a decomposition reaction. Hydrogen peroxide is catalyzed by manganese dioxide to produce water and oxygen, and the chemical equation is 2H2O2 mNO22H2O+O2, the reactant is one, and the product is two, which belongs to the decomposition reaction; Zinc particles and sulfuric acid react to form zinc sulfate and hydrogen, and the chemical equation is Zn+H2SO4 ZnSO4+H2
So the answer is: 2H2O2 Mno22H2O+O2, decomposition, disadvantage Zn+H2SO4 ZNSO4+H2

Hydrogen peroxide and manganese dioxide react to produce oxygen and water (which can also decompose on their own).
Similarly, under the addition of Kaire Tiaoxun Town, potassium crude acid per mu of high manganese can decompose oxygen, and potassium chlorate and manganese dioxide react to produce oxygen.
It's not compression, it's that it contains oxygen, which decomposes to produce oxygen.
Catalytic decomposition of hydrogen peroxide solution (the catalyst is mainly manganese dioxide, ferric oxide, copper oxide can also be): >>>More
Chemical formula: H2O2
Hydrogen peroxide is a liquid with two hydrogen atoms and two oxygen atoms in each molecule, which has strong permeability and oxidation, and is commonly used in medicine to clean wounds and local antibacterial. According to the latest research, hydrogen peroxide is not only a medical product, but also an excellent beauty product. >>>More
Hydrogen peroxide, scientific name is hydrogen peroxide solution, medical 3, used for disinfection, non-toxic, high efficiency, but has a potential carcinogenic effect, medical not 30, the concentration is too large, with strong corrosiveness, can be bleached and bleached.
