The valence of manganese is 4.
The name of MnO2-2 is manganese(IV) oxide.
Yes, MnO2 is the chemical formula for manganese (IV) oxide, also known as manganese dioxide. It is a black or brown solid commonly used as an oxidizing agent and in the production of dry-cell batteries.
Lol, you're probably in my chem class doing the same lab. I'm trying to figure out the same thing.
Yes: An oxide ion has a charge of -2. Two of them have a combined charge of -4, which is exactly neutralized by a manganese (IV) cation.
The chemical equation for this reaction is: 4HCl(aq) + MnO2(s) -> MnCl2(aq) + 2H2O(l) + Cl2(g) 2SO3(g) Explanation: Hydrochloric acid (HCl) reacts with manganese (IV) oxide (MnO2) to form manganese chloride (MnCl2), water (H2O), chlorine gas (Cl2) and sulfur trioxide (SO3) gas.

MnO2 is Manganese (IV) Oxide. It is also known as manganese dioxide, manganese oxide or as the naturally occurring mineral pyrolusite. Please see the related links below.
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.
It's a chemical reaction between zinc and manganese (IV) oxide (Zn/MnO2).

Manganese (III) Oxide
The chemical equation for this reaction is: 4HCl(aq) + MnO2(s) -> MnCl2(aq) + 2H2O(l) + Cl2(g) 2SO3(g) Explanation: Hydrochloric acid (HCl) reacts with manganese (IV) oxide (MnO2) to form manganese chloride (MnCl2), water (H2O), chlorine gas (Cl2) and sulfur trioxide (SO3) gas.
HCl(aq) + MnO2(s) yield MnCl2(aq)+H2O(l)+Cl(g)This is not a balanced equation. The complete answer should be:4HCL(aq) + MnO2(s) ----> MnCl2(aq) + 2H2O(l) +Cl2(g)
It means you have some manganese(IV) oxide. This compound most often shows up in chemical equations as a catalyst. It is most popularly used as a catalyst in the decomposition of hydrogen peroxide (H2O2.) A catalyst speeds up a chemical reaction by lowering the reaction's activation energy. In the equation for a chemical reaction, the catalyst is written in superscript-small symbols above the "yield" arrow.
