Step-by-step explanation:

The reaction is given as:

H₂S + O₂ → SO₂ + H₂O

Let us balance the chemical equation.

We take some letters and we use them as the coefficient to balance the equation;

aH₂S + bO₂ → cSO₂ + dH₂O

Now,

Conserving H;

2a = 2d

Conserving S;

a = c

Conserving O;

2b = 2c + d

Let a = 1, d = 1, c = 1, b =
`(3)/(2)` and multiply through by 2;

a = 2, b = 3, c = 2 and d = 2

So, the balanced reaction equation is given as;

2H₂S + 3O₂ → 2SO₂ + 2H₂O
