Which of the following oxide(s) of iron would be obtained on the prolonged reaction of iron with steam?
FeO
Fe₂O₃
Fe₃O₄
Fe₂O₃ and Fe₃O₄

Academic Chemistry NCERT Class 10

Correct Answer: (c) Fe304

Explanation: Iron reacts with steam (H₂O) to give ferric oxide and hydrogen gas is evolved. The reaction is given as:

$3Fe(s) + 4H_2O(g) \rightarrow Fe_3O_4(s) + H_2(g)$
