In the reaction, 8 A l + 3 F e 3 O 4 → 4 A l 2 O 3 + 9 F e , the number of electrons transferred from reductant to oxidant is

Correct answer

24

Step-by-step solution

12 H 2 O + 8 A l → 4 A l 2 O 3 + 24 H + + 24 e - 24 H + + 3 F e 3 O 4 + 24 e - → 9 F e + 12 H 2 O 24 electrons are transferred from reductant to oxidant.
