What is the number of iron atoms and hydrogen atoms in the balanced eq...
When Iron (Fe) reacts with the steam, it gives Iron Oxide with water. Iron not reacts with hot or cold water. It only reacts with the steam.
If you balance this chemical equation, you will get,
3Fe + 4H2O –> Fe3O4 + 4H2↑
Now, the right answer is Option-B.
Note:- When Iron reacts with water in the presence of steam, in balanced chemical equation, iron should be three atoms, and Oxygen should be four atoms in the left side of the equation.
If you balance this chemical equation, you will get,
3Fe + 4H2O –> Fe3O4 + 4H2↑

What is the number of iron atoms and hydrogen atoms in the balanced eq...
Balanced equation for the reaction of steam on iron is:
Fe + H₂O → Fe₃O₄ + H₂
To find the number of iron atoms and hydrogen atoms in the equation, we need to analyze the coefficients of each element in the equation.
- Iron (Fe): There are 3 Fe atoms on the left-hand side (reactants) and 3 Fe atoms on the right-hand side (products).
- Hydrogen (H): There are 2 H atoms on the left-hand side and 8 H atoms on the right-hand side.
To balance the equation, we need to multiply the reactants and/or products with suitable coefficients to make sure that the number of atoms of each element is equal on both sides.
- Iron (Fe): Since there are already 3 Fe atoms on both sides, we don't need to do anything.
- Hydrogen (H): We have 2 H atoms on the left and 8 H atoms on the right, so we need to multiply the H₂O molecule on the left by 4 to get 8 H atoms on both sides.
The balanced equation becomes:
3Fe + 4H₂O → Fe₃O₄ + 8H
Therefore, the answer is option A, which shows that the balanced equation has 3 Fe atoms and 8 H atoms.
Fe + H₂O → Fe₃O₄ + H₂
