Answer 1

Formulas and Oxidation States of Manganese

To determine the oxidation state of manganese (Mn) in different compounds, we need to match the formulas with the corresponding oxidation states. Let's go through each compound and its oxidation state:

1. MnO2 (A): The compound MnO2 is manganese dioxide. In this compound, the oxidation state of manganese is +4. [[1]]

2. MnCl2 (B): The compound MnCl2 is manganese(II) chloride. In this compound, the oxidation state of manganese is +2. [[2]]

3. KMnO4 (C): The compound KMnO4 is potassium permanganate. In this compound, the oxidation state of manganese is +7. [[3]]

4. KMnO4 (D): The compound KMnO4 is potassium permanganate. In this compound, the oxidation state of manganese is +7. [[3]]

Therefore, the correct matching of formulas and oxidation states of manganese is:

A) MnO2 - +4 B) MnCl2 - +2 C) KMnO4 - +7 D) KMnO4 - +7
