Manganese (Mn) in Mn3O4 has an oxidation state of +3. Each oxygen atom has an oxidation state of -2, so the total negative charge from oxygen is -8. To balance the charge, the three manganese atoms must have a total positive charge of +8, making each manganese atom have an oxidation state of +3 in Mn3O4.
What else can I help you with?
How many manganese atom are a liberated if 54.8 moles of Mn3O4 react with excess aluminum?
The balanced equation for the reaction is: 3Mn3O4 + 8Al -> 9Mn + 4Al2O3. This shows that 3 moles of Mn3O4 produce 9 moles of Mn. Thus, 54.8 moles of Mn3O4 would produce 9 * (54.8/3) = 164.4 moles of Mn atoms.
What is the oxidation number of each atoms Mn?
The oxidation number of manganese (Mn) can vary depending on the compound it is in. In MnO2, the oxidation number of Mn is +4, while in KMnO4, the oxidation number of Mn is +7.
What is the oxidation number of MN in 2MnO4-?
I assume you mean the oxidation number of Mn in the permanganate ion , MnO4- The sum of the oxidation numbers is the charge on a polyatomic ion so Mn has an oxidation number of +7 as each O is assigned -2.
What is the oxidation number of Mn in 2MnO2?
In MnO2, the oxidation number of oxygen is typically -2. Since there are two oxygen atoms in MnO2, the total oxidation number contributed by oxygen is -4. The overall charge of the compound is neutral, so the oxidation number of manganese (Mn) can be calculated by setting the total oxidation number equal to zero. Therefore, the oxidation number of Mn in 2MnO2 is +4.
What is the oxidation state for manganese in Mn?
The oxidation state for manganese in Mn is 0, since it is in its elemental form.

What is the oxidation state of of Mn in the compound Mn2?
The oxidation state of Mn in the compound Mn2 is +2. Each Mn atom has an oxidation state of +2, as indicated by the subscript 2 in the formula Mn2.
What is the oxidation number of MnCo2?
In MnCo2, Mn has an oxidation number of +2, and Co has an oxidation number of -1. This is determined by assigning oxidation numbers based on rules for assigning oxidation numbers to each element in the compound.
What is the oxidation number of Mn?
Lets say the oxidation number of Mn is x oxygen's oxidation number is -2 and the charge on the molecule is 1- so: 1(x) + 4(-2) = 0 x - 8 = 0 x = +8 and then you must remember that there is a negative charge to the molecule. Subtract 1. therefore oxidation number on Mn is +7
Oxidation number of mn in mno4-?
The oxidation number of Mn in MnO4- is +7. This is determined by balancing the charge of the whole ion (-1) with the charges of the oxygen atoms (-8) and solving for the oxidation number of Mn.
What are the oxidation numbers of mn(clo4)3?
The oxidation number of Mn in Mn(ClO4)3 is +7. Each Cl has an oxidation state of -1 and each O has an oxidation state of -2. The sum of the oxidation numbers should equal the charge of the molecule, which is 0 in this case.
What is the oxidation of Mn in Mn(ClO4)3?
The oxidation state of Mn in Mn(ClO4)3 is +7. This is because the overall charge of the perchlorate ion (ClO4)- is -1, and there are 3 perchlorate ions in Mn(ClO4)3, resulting in a total charge of -3. To balance this, the Mn ion must have an oxidation state of +7.
