62 When Fe and steam react at high
temperatures, the following reaction takes place

3 Fe (s) + 4 H2O (g) → Fe3O4
(s) + 4 H2 (g)
[Fe = 56, H = 1, O = 16]

How much iron must react with excess steam to form 928 g of
Fe3O4 ?
(1) 672 g (2) 448 g
(3) 560 g (4) 504 g

Dear Student,

Iron react with steam to form ferric oxideReaction is given below: 3Fe +  4H2O (g) ---> Fe3O4(s) + 4H2232 g of   Fe3O4 is formed when = 3×56 g of Fe react with steamSo, 928 g of   Fe3O4 is formed when = 3×56 232×928g of Fe react with steam928 g of   Fe3O4 is formed 672 g of Fe react with steamRegards
