If you had the equation of H2O2(aq) ==> H2O(l) + O2(g), it wouldn't be balanced, so is incorrect. If it were 2H2O2 ==> 2H2O + O2, then it would be balanced, and H2O2 would be an example of a disproportionation reaction, where H2O2 is both the oxidizing and reducing agent, i.e., the O is both oxidized and reduced to form H2O and O2. Not sure if this is what you are looking for as the question is rather vague.
2 H2O2 ---> 2 H2O + O2 + energy, it's exothermic
Actually, manganese dioxide is a catalyst that speeds up the reaction but does not get consumed in the reaction and is not part of the reactants or products
NO!!!! H2O2 is hydrogen peroxide H2O is water. Note there is a difference of one atom of oxygen.
H2o2
H2O2 (hydrogen peroxide) is a compound.
2 H2O2 ---> 2 H2O + O2 + energy, it's exothermic
No. It would have to be H2O2 - H2 = O2 in order to be balanced.
Hydrogen peroxide is a chemical compound also called H2O2.
The simplified chemical reaction is:H2 + O2 = H2O2

The decomposition of hydrogen peroxide produces water and oxygen. 2H2O2(l) -->2H2O(l) + O2(g)
NO!!!! H2O2 is hydrogen peroxide H2O is water. Note there is a difference of one atom of oxygen.
H2o2
H2O2 (hydrogen peroxide) is a compound.
no
H2O2 + 2 KI --> 2 KOH + I2
The balanced equation for this decomposition reaction is 2 H2O2 -> 2 H2O + O2.
