Answer 2

The reaction of So2 with H2S.

                      $2H_{2}S + So_{2}$   ⇒    $2H_{2}O + 3S$

The reaction of So2 with FeCl2

                  $4FeCl_{2} + So_{2} + 4HCl$   ⇒    $4FeCl_{2} + 2H_{2}O +S$

Explanation:

• when the hydrogen sulfide ($H_{2} S$) reacts with sulfur dioxide ($So_{2}$) then it gives hydrogen dioxide ($HO_{2}$) and solid sulphur ($3S$).
• similarly, when ($So_{2}$) reacts with ($FeCl_{2}$) then it gives ($FeCl_{3}$)  and sulphur as products.
• in both reactions water ($H_{2}O$) comes along as products
