When the Maganese Dioxide (black powder) was added to the Hydrogen Peroxide (clear), it bubbled.
It creates Water and Oxygen gas.
The reaction is Decomposition.
Hydrogen Peroxide --> Water + Oxygen
2Hâ‚‚Oâ‚‚ --> 2Hâ‚‚O + Oâ‚‚
When you write the reaction, make sure you put manganese dioxide over the yield symbol because it is a catalyst.
Manganese dioxide catalyzes the decomposition of hydrogen peroxide, to Water and oxygen:
2 H2O2 ---MnO2---> 2 H2O + O2

∙ 13y agoMore commonly, it's done the other way around; MnO2 is added in small amounts to a larger volume of H2O2. 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. Adding a small amount of hydrogen peroxide to a larger quantity of manganese dioxide would quickly (perhaps violently, depending on the concentration of the H2O2) release oxygen and leave a black, muddy mass of wet (but otherwise unchanged) MnO2.

your welcome!! hi my name is Kiran, i know i was having difficulties with this too, but now i know!!

Why sand didn't react to hydrogen peroxide?
Sand does not contain any enzymes or catalysts to decompose hydrogen peroxide
What is the chemical formula for Hydrogen oxide?
H2oThe symbol for hydrogen oxide is HO2H2O Because Hydrogen Oxide can be water.The most common meaning of Hydrogen oxide is Water which has formula H2O. Though there are some other Oxides of Hydrogen :> Hydrogen peroxide = H2O2> Hydroperoxyl = HO2> Trioxidane = H2O3Heres the real formula since the last answer may have not got the point across H subscript 2, O (H2O) is the the answer. Its just water!Hydrogen and oxygen carry charges of +1 and +2 respectively. When they react the typical oxide they form is in fact H2O, called hydrogen oxide which is commonly known as water.H2oHO2Hydrogen oxide is an unofficial name for water (it has several unofficial names) so its chemical symbol is H2O.
What do you get when you combine acetone and hydrogen peroxide?
The acetone and hydrogen peroxide would react with each other to make the high explosive acetone peroxide. An acid such as hydrochloric is commonly used in the synthesis of acetone peroxide, which speeds up the formation if it.
How do you neutralized nitrogen dioxide gas?
what you can do is to have it react with hydrogen peroxide at low temperature. When these react you get nitric acid: 2NO2 + H2O2 -> 2HNO3
Does cold liver react with hydrogen peroxide?
yes, but it will be a small reaction and proceed very slow
Reaction of aluminum oxide with hydrogen?
Aluminium oxide doesn't react with hydrogen.
Why sand didn't react to hydrogen peroxide?
Sand does not contain any enzymes or catalysts to decompose hydrogen peroxide
How does liver react with hydrogen peroxide?
test it and find out
Why does ground up meat react more than unground meat in hydrogen peroxide?
The ground meat has more surface area available to react with the hydrogen peroxide.
What is the reaction product of Fentons reagent with silver?
The reaction product of Fenton's reagent (a solution of hydrogen peroxide and ferrous iron) with silver is typically silver oxide (AgO) or silver hydroxide (AgOH) depending on the conditions of the reaction. These products are formed when the silver ions present in the solution react with the hydroxyl radicals generated by Fenton's reagent.
Is thorium and hydrogin peroxide dangerous if mixed?
Thorium (as a metal) doesn't react with hydrogen peroxide.

What will happen when potassium iodide react with hydrogen per oxide?
This reaction decomposes Hydrogen peroxide into Water and Oxygen: Here is the stepwise process:1> Hydrogen peroxide oxidizes the Potassium iodide into another salt called Potassium Hypoiodite, and itself gets reduced to water.H2O2 + KI----> KIO + H2O2>This salt is quite unstable and rapidly reacts with Hydrogen peroxide. Here the Peroxide ions disproportionates into Oxide ions and Molecular Oxygen gas.H2O2 + KIO ----> KI + H2O + O2So the overall reaction an be written as:H2O2 --KI--> H2O + O2
Will hydrogen peroxide lower chlorine level in hot tub?
Hydrogen peroxide react with chlorine.The reaction is the following:H2O2 + Cl2 = 2 HCl + O2
