Choose correct statements.

Options

A. In the balanced redox reaction `xAs_(2)S_(3)+yNO_(3)^(-)+4H_(2)O to aAsO_(4)^(3-)+bNO+cSO_(4)^(2-)+8H^(+)` molar ratio of x:y=3:28
B. when `NH_(4)SCN` oxidizes into `SO_(4)^(2-),CO_(3)^(2-) " and " NO_(3)^(-)` its equivalent weight will be `M/(24)`
C. when `Bi_(2)S_(3)` converted into `Bi^(5+)` and S, n-factor will be 7
D. Equivalent weight of `H_(3)PO_(2)` when it disproportionates into `PH_(3)" and " H_(3)PO_(3) " is "3(M)/(4)`
