Question

When Fe_0.93O is heated in presence of oxygen, it converts to Fe₂O₃. The number of correct statement/s from the following is _______.

A. The equivalent weight of Fe_0.93O is \(\frac{\text{Molecular weight}}{0.79}\).

B. The number of moles of Fe²⁺ and Fe³⁺ in 1 mole of Fe_0.93O is 0.79 and 0.14 respectively.

C. Fe_0.93O is metal deficient with lattice comprising of cubic closed packed arrangement of O^2– ions.

D. The % composition of Fe²⁺ and Fe³⁺ in Fe_0.93O is 85% and 15% respectively.

Answer 1

Answer is 4

A : Fe_0.93O → Fe₂O₃

C : Fact

D : %Fe²⁺ = \(\frac{0.79}{0.93}\) x 100 = 85% ; Fe³⁺ = 15%
