Answer»


Solution :A) `2H_(2)S +SO_(2) to 2H_(2)O+3S` (Oxidizing NATURE)
`SO_(2)+2H_(2)O+Cl_(2) to 2HCl+H_(2)O` (REDUCING agent)
`2NaOH+SO_(2) to Na_(2)SO_(3)+H_(2)O` (acidic nature)
`SO_(2)+2H_(2)O to H_(2)SO_(4)+2(H)` (BLEACHING agent)
B) `SO_(3)+H_(2)O to H_(2)SO_(4)` (Acidic nature)
`SO_(3)+2HBr toH_(2)O+Br_(2)+SO_(2)` (Oxidisingagent)
C) `PbS +4O_(3) to PbSO_(4)+4O_(2)` (OXIDISING agent)
`BaO_(2)+O_(3) to BaO+O_(2)` (Reducing nature)
