MnO2 is the chemical formula(there is no equation). The compound is called manganese oxide and manganese(IV) oxide by IUPAC. Wikipedia calls it manganese dioxide.
Manganese is an element. "Chemical equations" do not apply to an element all by its lonesome, so what are you referring to?
There isn't a "chemical equation for manganese". (It is an element.) The symbol for manganese is Mn.
The overall chemical reaction is:Zn + 2 MnO2 = ZnO + Mn2O3
The chemical formula of this is MnO2.It is brown in colour. The oxidation number of Mn is 4 in this compound.
A chemical reaction is represented by a chemical equation.
such a compound is an oxidizing agent as , KMnO4 , K2Cr2O7 , K2CrO4 ,MnO2 , H2O2 etc.
A chemical equation is the graphic expression of a chemical reaction.
Well, tne chemical formula is MnO2. If you mean the name of it, that is manganese dioxide.

MnO2
chemical change
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)
MnO2 is the most common version
Only by chemical analysis.
2H2O2 + MnO2 --> 2H2O+O2 + Mn
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.
Manganese dioxide is itself a compound with formula = MnO2
Con HCl & MnO2
The overall chemical reaction is:Zn + 2 MnO2 = ZnO + Mn2O3
