How many water molecules are required to react with three molecules of the iron atom to form $$Fe_3O_4$$ ?​

Correct option is A

Correct Answer: (A) 4

To determine how many water molecules react to form Fe₃​O₄​, we consider the balanced chemical equation for the formation of Fe₃O₄from iron and water.

Reaction:

3Fe+4H₂O→Fe₃O₄+4H_{2 ​}

Explanation:

• Reactants: Three iron (Fe) atoms react with four water (H₂O) molecules.
• Products: This reaction produces one molecule of Fe₃O_4​ and four molecules of hydrogen gas (H₂).

Conclusion:

The number of water molecules required to react with three molecules of iron to form Fe₃O₄​ is 4.
