Question

balance the following chemical equation:
Fe + H2O - Fe3O4 + H2

Answer 1

Heya
Here is your answer
_____________________________________________________________

Fe + H₂O ⇒ Fe₃O₄ + H₂

3Fe + 4H₂O ⇒ Fe₃O₄ + 4H₂

We balanced it by hit and trial method.......the no. of atoms on reactants and products are equal

Hope it helps! ^_^

Answer 2

The balanced equation is 3Fe + 4H2O - Fe3O4 + 4H2.

• First balance the Fe atoms.
• One side has 3 Fe atoms while another side has only one. so, multiply 3 where Fe is only 1.
• Similarly, one side has 4 Oxygen atoms while another side has only one. so, multiply 4 where O is only 1.
• Now, balance the hydrogen atoms.
• One side has 8 atoms while another side has only two. so, multiply 4 where hydrogen is 2.
• Hence, the balanced equation is 3Fe + 4H2O - Fe3O4 + 4H2.
