Question

Give complete explanation of different phases to balance the reaction Fe + H2O → Fe304 + H2.
​

Answer 1

$hello$

Let us consider the problem:

Reaction:

Fe+H2O→Fe3O4+H2

 reactant                Products

Fe=1                 Fe=3

H=2                  H=2  

O=1                   O=4

Then,balance chemical equation is 

3Fe+4H2O→Fe3O4+4H2

I hope my answer helps you.....✌
