total number of electrons transferred during reaction are:

Open in App

Solution

In the given reaction, $A l$ is oxidised to 0 to +3 oxiation and $F e$ is reduced to $+ \frac{8}{3}$ to $0$ .
Complete balanced equation: $8 A l + 3 F e_{3} O_{4} ⟶ 4 A l_{2} O_{3} + 9 F e$
In the reaction no.of $A l$ is $8$ . So, number of electrons are transferred is $8 \times 3 = 24$
