Question

Which of the following correctly represents a balanced chemical equation?

Options

• Fe(s) + 4H₂O(g) → Fe₃O₄ (s) + 4H₂(g) 

• 3Fe(s) + 4H₂O(g) → Fe₃O₄ (s) + 4H₂(g)

• 3Fe(s) + H₂O(g) → Fe₃O₄ (s) + H₂(g)

• 3Fe(s) + 4H₂O(g) → Fe₃O₄ (s) + H₂(g)

Answer 1

3Fe(s) + 4H₂O(g) → Fe₃O₄ (s) + 4H₂(g)
