Which balanced equation represents an oxidation-reduction reaction?

Oxidation states are used in chemistry solutions. It is a bond in which electron transfers easily from one nucleus to another nucleus.

Explanation:

Oxidation-reduction reactions have some rules. The oxidation state is 0 at an uncombined bond. The bond of oxidation reduction is + 1 in alkeli metal. The bond in two metal is + 2 The oxidation reduction state at helogens is - 1. It does not happened always. The oxygen bond in oxidation and reduction is - 2. The sum of the oxidation state is equal to the compound charges. In this process the changes occur for any elements. Redox could be occur. Its oxidized and reduction reaction can be seen in this process.
