SO2 is reducing /oxidizing and TeO2 is reducing/oxidising
SO2 is reducing teO2 is oxidizing
Reducing property of grp 16 oxides increases/decreases down the grp
decreasing
SF4,TeF4,SeF4 are Solid/liquid/gas
SF4:- Gas TeF4:- Solid SeF4:- Liquid
Why is SF6 exceptionally stable
steric reasons
Al2O3 with HCl
SO2+O2 forms and the catalyst used here is
it forms SO3 and the catalyst used V2O3
FeSO4 on heating forms
HSO4- on electrolysis forms
H2S2O8
Ozone color in gas,liquid,solid
gas: - pale blue liquid: - dark blue solid: - violet-black
NO with O3 forms
NO2 + O2
Alpha S color and how is it formed
yellow color formed on evaporation the solution on roll sulphur in CS2
