Question

how to balance fe+h2o=fe3o4+h2

Answer 1

Hey,
Here's ur answer..

Answer 2

first take fe3o4 the complex compound
and than see no of fe atom in ur rhs
it's 1 so use coefficient 3 in front of fe

now it's become
3fe +h20=fe3o4 +H2
now u need to balance o
so use coefficient 4 in front of h2o as oxygen atom in lhs is 4



now it's become
3fe +4h20=fe3o4 +H2

now only hydrogen atom is unbalanced
so use 4 in lhs of H2 to balance it


now it's become
3fe +4h20=fe3o4 +4H2

now it's become balanced equation

hope !!!! this will help u
if yes!!! than mark these answer as brainliest
