Question

A battery is constructed based on the oxidation of magnesium and the reduction of cu2+. the initial concentrations of mg2+ and cu2+ are 1.2×10−4 m and 1.44 m , respectively, in 1.0-liter half-cells. how long can the battery deliver 5.33 a before going dead?

Answer 1

14.48 hrs

Step-by-step explanation:

Considering what is given;

Let Cu^2+ be the limiting reagent.

1.44×2×1= 2.88 mol of Cu^2+

Q= 2.88×96500= 277920C

I= 277920/5.33= 52142.58912 secs or 14.48 hrs
