Fe_2O_3, Fe_3O_4, FeS_2, Cu_2 O

When steam is passed over hot iron, hydrogen is liberated and Fe_(3)O_(4) is formed according to the chemical equation 3 Fe + 4 H_(2)O to Fe_(3)O_(4) + 4 H_(2)(g) . In a typical reaction, 56 g iron was consumed. Calculate the following: The mass of Fe_(3)O_(4) formed. (R.A.M. : H = 1, O = 16, Fe = 56)

In the following change, 3Fe + 4H_(2)O rarr Fe_(3)O_4 + 4H_2 If the atomic mass of iron is 56, then its equivalent mass will be :

Haematite is Fe_2O_3 / Fe_3O_4 .
