Determine the redox reaction represented by the following cell notation.
mg(s) / mg2+(aq) // cu2+(aq) / cu(s)

Explanation:

The given cell notation is:-

Oxidation reaction is defined as the chemical reaction in which an atom looses its electrons. The oxidation number of the atom gets increased during this reaction.

Reduction reaction is defined as the chemical reaction in which an atom gains electrons. The oxidation number of the atom gets reduced during this reaction.

The half cell reactions for the above cell notation follows:

Oxidation half reaction:  

Reduction half reaction:  

The overall redox reaction is:-

chemical digestion occurs in the stomach were hcl and pepsin forms chyme, the mouth in which salivary amylase breaks down starch to form bolus, and the small intestine specifically the duodenum.
