Question

how to find oxidation state of Mn2O​

Answer 1

Answer:

The oxidation number of the oxide anion is -2 . Since there are 2 oxide ions, the total oxidation number for the oxide is -4 . Since the sum of the oxidation numbers must be 0 , the oxidation number of the manganese cation is +4 . Therefore, MnO2 is the ionic compound manganese(IV) oxide.

Answer 2

Answer:

Oxidation state of Mn2o is +3

Explanation:

Since the oxidation state of oxygen is -2

Then assuming x is the oxidation state of Mn

2x + 3(-2) = 0

2x = 6

or x = +3
