The net redox reaction of a galvanic cell is given below
`2Cr(s) + 3Cu_((aq))^(2+) to 2Cr_((aq))^(3+) + 3Cu_((s))`
Write the half reactions and describe the cell using cell notation.

Explanation

Anodic oxidation : `2Cr_((s)) to 2Cr_((aq))^(3+) + 6e^(-)" " ….(1)`
Cathodic reduction : `3Cu_((aq))^(2+) +6c^(-) to 3Cu_((s))" " ….(2)`
Cell Notation is : `Cr_((s)) |Cr_((aq))^(3+)||Cu_((aq))^(2+)|Cu_((s))`.
