Chemistry - Redox Reactions Question with Solution | TestHub

According to the law of equivalents, the number of equivalents of all reactants and all products are equal. In the given reaction, if $a=x_F$ of Cu₂O, $b=x_F$ of Cu₂S, $c=x_F$ of Cu, and $d=x_F$ of SO₂)

then find the value of $(a+b+c+d)$.

$$C{u}_{2}O(s)+C{u}_{2}S(s)⟶Cu(s)+S{O}_2(g)$$

$x_F$ = Number of electrons lost or gained by one particle of a chemical species.
