H2O2, or Hydrogen Peroxide is combined with MnO2, Manganese Dioxide, to form H2O, water, and O2, oxygen gas. The Manganese Dioxide serves as a catalyst in this reactions since it is not a reactant, but sets the reaction in motion. Therefore, when writing the chemical equation, one should place MnO2 beneath the yield sign.
One's balanced chemical equation should look like this:
a. 2H2O2(L) ==> 2H2O(L) + O2(g)
MnO2(s)

How fast does hydrogen peroxide solution break down?
This depends on a variety of factors such as temperature, the strength of the hydrogen peroxide solution and the presence or not of a catalyst, like manganese dioxide or silver. Acidic solutions also exhibit better stability. So, a slightly acidic and weak solution of hydrogen peroxide, stored in a cool place, will break down the slowest. Hydrogen peroxide decomposes to form water and oxygen, liberating heat in the process.
What is the product of hydrogen peroxide and manganese dioxide?
Manganese dioxide will catalyze the release of oxygen when added to hydrogen peroxide. The peroxide, H2O2, becomes H2O + O. The oxygen escapes as a gas, leaving water. The manganese dioxide remains unchanged. Concentrated hydrogen peroxide reacts very rapidly, even violently, when MnO2 is added; but a dilute solution will release its oxygen more slowly and steadily; making it useful as an oxygen generator for laboratory experiments.
Does hydrogen peroxide come in powder form in a bottle?
No. Even pure hydrogen peroxide is a liquid. Pure H2O2 is not commercially available as it is extremely reactive, making it too dangerous for the general public.
Hydrogen peroxide breaks down into water and oxygenexplain why this is a chemical reactionwhat are the reactants and products in the reaction?
The chemical reaction is caused because it is not possible to rearrange water and oxygen to form hydrogen peroxide. This is taught in science.
What type of chemical reaction is it when hydrogen peroxide break apart to form water and oxygen?
Decompisition reaction

What compound reduced by hydrogen1 cobalt oxide 2 mangnese dioxide 3 magnesium oxide 4 calcium oxide?
Cobalt oxide can be reduced by hydrogen to form cobalt metal. Manganese dioxide can be reduced by hydrogen to form manganese metal. Magnesium oxide cannot be reduced by hydrogen. Calcium oxide cannot be reduced by hydrogen.
What is hydrogen peroxide solution?
an aqueous form of hydrogen peroxide H2O2 (aq)
Is hydrogen peroxide the same as peroxide?
Peroxide is an compound that can be a part of another chemical to form a molecule. Hydrogen peroxide is two hydrogen atoms attached to a peroxide molecule, forming hydrogen peroxide. Peroxide itself (O2) only exists as molecular oxygen when it is not attached to another chemical.
If you use 30 percent percent hydrogen peroxide and manganese where does the hydrogen go to?
The two hydrogen atoms remain bound to a single oxygen atom to form water while the oxygen released by the manganese-facilitated decomposition of the hydrogen peroxide molecule pairs up with another oxygen atom to form gaseous oxygen. The catalyzed decomposition reaction of 30% H2O2 at ordinary conditions is quite vigorous and most of the contents of the container will end up on the table, ceiling and walls. DO NOT SEAL THE REACTION VESSEL! (...unless it is a rubber balloon,)
Does sunlight help form hydrogen peroxide in rainwater?
Sunlight will degrade any hydrogen peroxide that is in the water. This is why over-the-counter hydrogen peroxide is sold in brown bottles.
Is the element hydrogen and oxygen combine to form hydrogen peroxide a chemical change?
Yes it is.
Does hydrogen peroxide contain nitric acid?
No, hydrogen peroxide and alcohol are two very different substances.
Is hydrogen peroxide a compound orca mixture p?
Hydrogen peroxide is a compound, but it is too unstable to exist in pure form undermost conditions. Therefore, when encountered in a laboratory or during medical treatment, hydrogen peroxide is almost always a mixture with water.
What is the peroxide ion formula?
The chemical formula for hydrogen peroxide is H2O2. It consists of two hydrogen and two oxygen atom per molecule of hydrogen peroxide. Hydrogen peroxide decomposes rapidly at high temperatures to water and oxygen gas.
What 2 compounds form when hydrogen is combined chemically with oxygen?
Water, H2O, or hydrogen peroxide, H2O2.
