Question

I Reckin' That we use them Redox Way of Doin' These, or sumthin like that:
A) Mn O2 + H2 SO4 + H2 C2O4
B) SbCl5 + 2KI >>>> SbCl3 + 2KCl + I2 << done, but is it right?
C) S + HNO3 >>>> SO2 + NO +H2O
D) HNO2 + HI >>>> NO + I2 + H2O

Answer 1

A) MnO2 + H2SO4 + H2C2O4 (this is not complete?)

B) SbCl5 + 2KI >>>> SbCl3 + 2KCl + I2 (yes it's good)

C) 3S + 4HNO3 >>>> 3SO2 + 4NO +2H2O

D) 2HNO2 + 2HI >>>> 2NO + I2 + 2H2O
