Ответ:

X = FeSO4 (сульфат железа (II)), Y = HNO3 (нитрид кислоты)

Уравнения реакций:

Fe + H2SO4 → FeSO4 + H2

FeSO4 + HNO3 → Fe(NO3)3 + H2SO4

Fe(NO3)3 → FeO + NO2 + NO + O2

X = Fe(OH)2 (гидроксид железа (II)), Y = HCl (хлорид кислоты)

Уравнения реакций:

Fe + 2HCl → FeCl2 + H2

FeCl2 + NaOH → Fe(OH)2 + 2NaCl

Fe(OH)2 → Fe(OH)3 + H2O

2Fe(OH)3 → Fe2O3 + 3H2O

X = Fe(NO2)2 (нитрит железа (II)), Y = HNO2 (нитрознокислота)

Уравнения реакций:

Fe + 2HNO3 → Fe(NO2)3 + H2O

Fe(NO2)3 → FeO + NO2 + NO + O2

X = FeCl2 (хлорид железа (II)), Y = HCl (хлорид кислоты)

Уравнения реакций:

Fe + 2HCl → FeCl2 + H2

FeCl2 + HCl → FeCl3

FeCl3 + NaOH → Fe(OH)3 + NaCl

Fe(OH)3 → Fe2O3 + 3H2O
