Question

SO₂(g) + H₂S(aq) → S(s) + H₂O (1) , Balance the equation stepwise

Answer 1

SO₂(g) + H₂S(g) → S(s) + H₂O(l)

Step 1 :- balance oxygen by multiplying 2 with H₂O(l)
e.g., SO₂ + H₂S → S + 2H₂O

step 2 :- balance hydrogen by multiplying 2 with H₂S
e.g., SO₂ + 2H₂S → S + 2H₂O

step 3 :- balance sulphur by multiplying 3 with S
e.g., SO₂ + 2H₂S → 3S + 2H₂O

Could you check , SO₂ + 2H₂S → 3S + 2H₂O is balance or not ?
of course , it is balanced chemical equation.

Hence, SO₂ + 2H₂S → 3S + 2H₂O is balanced equation of given skeleton equation.
