mg07 *********************2nd Opinion**************** Nope, it is Mn2O7
The oxidation number of Mn in manganese VII oxide is +7. This is because oxygen typically has an oxidation number of -2, and there are two oxygen atoms in manganese VII oxide, giving a total oxidation number of -4. To balance the compound's charge of 0, manganese must have an oxidation number of +7.
Mn+7 P-3 = Mn3P7

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+
In currency terms, "mn" stands for "million." Therefore, when you see "USD mn," it refers to an amount in U.S. dollars expressed in millions. For example, 5 USD mn would mean 5 million U.S. dollars, or $5,000,000.
Manganese oxidation state = +7 So, it is also called Manganate(VII)

When potassium manganate VII reacts with iron II sulfate, the purple color of potassium manganate VII will change to a pale pink or colorless solution due to the reduction of MnO4- to Mn2+. The iron II sulfate solution will become a pale green color due to the formation of Fe2+ ions.
This is a worldwide community to answer questions. You will have to define the meaning of "Mn". Is that supposed to mean something or was that a typo?
