Question

FexOy + H2SO4 →

.M + HNO3 →

MxOy + HNO3 →

 

Answer 1

FexOy + H2SO4 → Fe(NO3)3 + S + H2O

.M + HNO3 → M(NO3)n + NO + H2O

.MxOy + HNO3 → M(NO3)n + NO + H2O
 

Answer 2

2FexOy+(6x-2y)H2SO4 ---> xFe2(SO4)3 + (3x-2y) SO2+ (6x-2y)H20

(5x-2y)M + (6nx-2ny)HNO3 → (5x-2y)M(NO3)n + nNxOy + (3nx-ny)H2O

3MxOy + (4nx - 2y)HNO3 ---> 3xM(NO3)n + (nx - 2y)NO + (2nx - y)H2O
