In this case the roman numerals indicate the oxidation state of the cation portion of the polyatomic ion: [Fe(II)O2]2- as opposed to [Fe(III)O2]1- Mn(II)=Mn2+
Mn(VII)=Mn7+

What compound is more acidic Mn2O7 or MnO2?
Mn2O7 is more acidic than MnO2. This is because Mn2O7 is a peroxide compound that contains more oxygen atoms and can release more H+ ions when dissolved in water, making it a stronger acid than MnO2.
Why Roman numerals must be included in the names of MnO2 and Mn2O7?
Roman numerals indicate the oxidation state of the metal in the compound. In MnO2, manganese has an oxidation state of +4, so it is represented as manganese(IV) oxide. In Mn2O7, manganese has an oxidation state of +7, so it is named manganese(VII) oxide. Including Roman numerals ensures clarity about the oxidation state of the metal ion in the compound.
Is MnO2 a compound?
Yes, MnO2 is a compound, manganese dioxide.
Hydrogen peroxide H2O2 can be quickly decomposed using MnO2 water and oxygen result MnO2 which is unchanged can then be filtered out of the solution MnO2 is the what?
Catalyst.
Rank these items in order of increasing oxidation number for manganese Mn KMnO4 MnO2?
MnO2: oxidation number +4KMnO4: oxidation number +7
What is the name of MnO2-2?
The name of MnO2-2 is manganese(IV) oxide.
What is the charge of MnO2?
The charge of MnO2 is typically +4 because oxygen is typically assigned a charge of -2, and there are two oxygen atoms in MnO2. This means the manganese atom in MnO2 must have a charge of +4 to balance the charges.
Why is MnO2 called manganese IV oxide?
MnO2 is called manganese IV oxide because manganese has a +4 oxidation state in this compound. The Roman numeral IV indicates that manganese is in the +4 oxidation state, where it has lost four electrons.
What is the formula for MnO2?
