An electrochemical cell is composed of pure nickel and pure iron electrodes immersed in solutions of their divalent ions. if the concentrations of ni2+ and fe2+ ions are 0.002 m and 0.40 m, respectively, what voltage is generated at 25°c? (the respective standard reduction potentials for ni and fe are −0.250 v and −0.440 v.) (a) −0.76 v (b) −0.26 v (c) +0.12 v (d) +0.76 v

C  0.12 V

Explanation:

Given

Concentration of

Concentration of

Standard Potential for Ni and Fe are  and

x+2 because it just doubles hon so the pattern can actually tell you the expression.

so for example,

if x=2 then 2+2 is 4

if x=4 then 4+4 is 8

and so on and so forth.

i really hope that this makes sense and you out in a way hon: )

import math

x=int(input("enter a number: "))

print (math.sqrt(math.fabs(
