Write a balanced chemical equation with state symbols for the following reaction: Heated iron metal reacts with steam to from iron (II, III) oxide, (Fe_(3)O_(4)) and hydrogen.

Large quantities of hydrogen are required these days in industry for various purposes. Water is found to be the industry raw material from which hydrogen can be obtained . One of the important methods for the commerical production of hyrogen in Lane's process in which steam is passes over hot iron. Iron decomposes steam with formation of magnetic oxide (Fe_(3)O_(4)) and hydrogen. (i) {:(3Fe,+,4H_(2)O,rarr,Fe_(3)O_(4),+, 4H_(2)),(,,"steam",,"magnetic ",,),(,,,,"oxide",,):} Iron is regenerated by reducing magnetic oxide with water gas (it is mixture of CO and H_(2) in 1:1 mole ratio). {:((ii),Fe_(3)O_(4),+,4CO,rarr,3Fe ,+,4CO_(2)uarr),((iii),Fe_(3)O_(4),+,4H_(2) ,rarr,3Fe,+,3H_(2)O),(,,,,,,,("Steam recovered")):} [equal amount sof magnetic oxide react in steps (ii) and (iii)] Steam so produced is again used in the previous step in which magnitic oxide is produced : [At . wt. implies Fe=56] if iron is recovered in (ii) an (iii) with 80% efficiency , then how many gram iron is recovered if initially 56 gm iron is taken?

The weight of iron which will be converted into its oxide (Fe_(3)O_(4)) by the action of 18 g of steam on it will be: (Atomic mass of Fe=56)

When 4g of iron is burnt to ferric oxide at constant pressure, 29.28KJ of heat is evolved. What is the enthalpy of formation of ferric oxide (At wt. of Fe=56 )
