Answer 1

QUESTION :-

for the oxidation of one mole of Fe3O4 number of electrons lost are:

ANSWER :-

The oxidation number of hydrogen changes from +1 (in water) to 0 (in hydrogen molecule).

Thus, net change in the oxidation number of hydrogen per atom is 1.

There are 8 H atoms.

Hence, the total change in the oxidation number of 8 hydrogen atoms is 8.

Hence, 8 electrons are involved in the redox reaction.

Hence, x=8.
