Separation Of Fe Feo And Fe O

  • a mixture of feo and fe3o4 when heated in air to

    Let us consider weight of FeO & Fe 3 O 4 be 'a' & 'b' gm respectively.. Consider the following reactions. 2 FeO + 1/2 O 2 -----> Fe 2 O 3 . Fe 3 O 4 + 1/2 O 2-----> 3Fe 2 O 3 . Molar mass of FeO =144 g and that of Fe 2 O 3 is 160 gms.. Thus 144 g FeO gives 160 g Fe 2 O 3 'a' g FeO will give 160 x a/144 gm Fe 2 O 3-----(1) . Similarly, weight of Fe 2 O 3 formed by 'b'gm Fe 3 O 4 = 160 x 3b

  • Fe + O2 = FeO - Chemical Equation Balancer

    Use uppercase for the first character in the element and lowercase for the second character. Examples: Fe, Au, Co, Br, C, O, N, F. Ionic charges are not yet supported and will be ignored. Replace immutable groups in compounds to avoid ambiguity. For example, C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but XC2H5 + O2 = XOH + CO2
