The number of electrons lost in the following change is
`Fe+H_(2)OrarrFe_(3)O_(4)+H_(2)`

A

2

B

4

C

6

D

8

Text Solution

Verified by Experts

The correct Answer is:
D
`Fe_(3)O_(4)-=FeO+Fe_(2)O_(3)`
Therefore, the change can be represented as
`FerarrFe^(2+)+2e^(-)`
`2Fe rarr2Fe^(3+)+6e^(-)`
`:.` Number of electrons transferred = 8.
