The equation is as below,
<span>5 Ag</span>⁺ (aq) + Mn²⁺ <span>(aq) + 4H</span>₂<span>O (l) → 5Ag (s) + MnO4</span>⁻<span>(aq) + 8H</span>⁺ <span>(aq)
Reduction:
According to eq. Silver is reduced as,
</span>
5 Ag⁺ + 5 e⁻ → 5 Ag
One electron is gained per Ag ion, so 5 Ag ions will gain 5 electrons.
Oxidation:
According to eq. Manganese is Oxidized as,
Mn²⁺ → MnO4⁻
Oxidation number of Mn in MnO₄⁻ is +7, so Mn²⁺ is loosing 5 electrons, Hence,
Mn²⁺ → MnO4⁻ + 5 e⁻
Results:
Hence, 5 moles of electrons are exchanged between oxidizing and reducing agents.

Hess’s Law makes it
possible to calculate ΔH for complicated chemical reactions. Moreover, the principle
claims that the entire amount of “enthalpy” when the development or progression
of a chemical reaction is complete whether the reactions are created in a
single or numerous processes, it still changes. This law is now described as
the principle of conservation of energy, and part of the thermodynamics law as
the first. </span>
