Question
In the reaction, 8Al + 3Fe3O4→4Al2O3 + 9Fe, the number of electrons transferred from reductant to oxidant is:
Answer: Option D
:
D
Elemental metallic Aluminium carries an oxidation number of 0.
From the products, we see that 0Al becomes 3+Al3+.
Clearly, Aluminium is the reducing agent.
There are 8 Aluminium atoms on the left and theyallbecome Al3+.
So overall, there are 24 electrons transferred.
