In the reaction, $8 A l + 3 F e_{3} O_{4} \to 4 A l_{2} O_{3} + 9 F e,$ the number of electrons transferred from reductant to oxidant is

Answer:

24.00

Solution:

$12 H_{2} O + 8 A l \to 4 A l_{2} O_{3} + 24 H^{+} + 24 e^{-}$
$24 H^{+} + 3 F e_{3} O_{4} + 24 e^{-} \to 9 F e + 12 H_{2} O$
24 electrons are transferred from reductant to oxidant.
