Answer:
this isn't correct answer but the equation is correct by using this methid you can got your answer .
Explanation:
Given - Mass number of atom = 23
Atomic number of atom = 11
As, no. of electrons in an atom is equal to an atomic number of the element.
So, number of electrons = 11
Secondly , number of protons are equal to number of electrons.
so, number of protons = 11
And number of neutrons = mass number - atomic number = 23−11 = 12
so, number of neutrons = 12
So , the atom contains 11 protons, 11 electrons, 12 neutrons.

Answer:
-36.67 KJ
Explanation:
Now, we ,must find the E°cell as follows;
E°cell= E°cathode - E°anode
E°cathode= -0.25 V
E°anode = - 0.44 V
E°cell= -0.25 -(- 0.44) = 0.19 V
Equation of the reaction; Ni2+ (aq) + Fe(s) → Ni(s) +Fe2+ (aq)
Hence, n=2, there were two electrons transferred.
ΔG=-nFE°cell
ΔG= -(2 * 96,500 * 0.19)
ΔG= -36670 J
ΔG= -36.67 KJ
