Answer» `SO_(2), SO_(3)` `SO, SO_(2)` `SO, SO_(3)` `S_(2)O, S_(2)O_(3)` Solution :`FeSO_(4).7H_(2)Ounderset(-7H_(2)O) overset(300^(@)C)to 2FeSO_(4) overset("high T")to Fe_(2)O_(3)+SO_(2)+SO_(3)`. `Fe_(2)(SO_(4))_(3)3NaOH to underset("Dirty GREEN ppt") (2Fe(OH)_(3)+Na_(2)SO_(4))` Oxides are `SO_(2),SO_(3)`.
