Question

manganese dioxide can difuse torch bulb

​

Answer 1

Answer:

Manganese(IV) oxide is the inorganic compound with the formula MnO

2. This blackish or brown solid occurs naturally as the mineral pyrolusite, which is the main ore of manganese and a component of manganese nodules. The principal use for MnO

2 is for dry-cell batteries, such as the alkaline battery and the zinc-carbon battery.[4]MnO

2 is also used as a pigment and as a precursor to other manganese compounds, such as KMnO

4. It is used as a reagent in organic synthesis, for example, for the oxidation of allylic alcohols. MnO

2 in the α polymorph can incorporate a variety of atoms (as well as water molecules) in the "tunnels" or "channels" between the manganese oxide octahedra. There is considerable interest in α-MnO

2 as a possible cathode for lithium ion batteries.[5][6]
