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

Options

A. FeO
B. `Fe_(2)O_(3)`
C. `Fe_(3)O_(4)`
D. `Fe_(2)O_(3)" and " Fe_(3)O_(4)`

Answer

C

Explanation

Reactions of iron metal with water
`underset("Iron (II) farric")(Fe(s))+underset("Steam")(H_(2)O)tounderset("Iron (II) oxide")(FeO)+H_(2)(g)uparrow`
`underset("Iron (III) farric")(2Fe(s))+underset("Steam")(3H_(2)O)tounderset("Iron (III) oxide")(Fe_(2)O_(3))+3H_(2)(g)uparrow`
`3Fe(s)+4H_(2)Otounderset("Iron (II, III) oxide")(Fe_(3)O_(4))+4H_(2)(g)uparrow`
