Manganese (Mn) has many possible oxidation numbers (+2 and +4 are just two of these). Write the correct formulas and names for the four compounds which combine manganese (in these oxidation states) with both bromine and oxygen.

Oxide of manganese, Potassium permanganate, Manganese bromide and manganese oxide.

Explanation:

1. Manganese dioxide

Its chemical formula is . It is +4 oxidation state. It is a black solid which is fairly stable.

2. Potassium permanganate

Its chemical formula is . It is commonly used in the laboratories as oxidizing agent. They appear black in color.

3 Manganese bromide

Its chemical formula is

4. Oxides of manganese

Chemical formula is

The most stable state of Manganese is +2 oxidation state.

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.
