Question

Fe_xO_y + HNO₃ → Fe(NO₃)₃ + NO + H₂O

Thay NO lần lượt bằng NO₂, N₂O, N₂, NH₄NO₃ rồi hoàn thành phản ứng

Answer 1

3FexOy + (12x-2y)HNO3 => 3xFe(NO3)3 + (3x-2y)NO + (6x-y)H2O FexOy + (6x-2y)HNO3 => x Fe(NO3)3 + (3x-2y) NO2+ (3x-y)H2O 10FexOy + (36x-4y)HNO3 => 10xFe(NO3)3 + (3x-2y)N2 + (18x-2y)H2O 8FexOy + (30x-4y)HNO3 => 8xFe(NO3)3 + (3x-2y)N2O + (15x-2y)H2O

Answer 2

1)

3FexOy + (12x-2y)HNO3→3xFe(NO3)3+(3x-2y)NO+(6x-y)H2O

2)

FexOy + (6x-2y) HNO3 = x Fe(NO3)3 + (3x-2y) NO2+(3x-y) H2O

3)

8FexOy + (30x-4y)HNO3 -> 8xFe(NO3)3 + (3x-2y)N2O + (15x-2y)H2O

4)

10FexOy + (36x-4y)HNO3 → 10xFe(NO3)3 + (3x-2y)N2 + (18x-2y)H2O
