Question

Need help with this please

Answer 1

`-3.06` is the overall voltage produced

Step-by-step explanation:

Potassium and Tin are connected in an electrochemical series.

In a series circuit, the resultant voltage is equal to the sum of voltage drops at all points in the circuit.

Here,

The voltage drop at potassium
`= -2.92`

The voltage drop at Tin
`= -0.14`

The net voltage

`= -2.92 -0.14 \\= -3.06`
