Answer:
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.
When air is hot, the the particles move much faster and when the air is cold the particles slow down as they are condensing
The answer is: dinitrogen triphosphide. This is because Tri means 3 and there are 3 phosphates, Di= 2 and there are 2 nitrogen’s.
the air molocules that are surrounding the metal will speed up, and the molocules in the metal will slow down, because as the metal cools the molocules will cool which would make them slow down, but then it would heat the surrounding air and make those molocules speed up.
