Question

If the supply of oxygen is limited, H2S reacts with O2 to form (A)  H2O+SO3  (B)  H2O+S  (C)  H2SO4+S  (D)  H2O+SO2

In limited supply of oxygen, H 2 S burns with blue flame and S and H 2 O are the main products. 2 H 2 S + O 2 longrightarrow 2 H 2 O +2 S In excess of oxygen, H 2 S gives SO 2 and water as main product.

Q. If the supply of oxygen is limited, $H_{2} S$ reacts with $O_{2}$ to form

$H_{2} O + S O_{3}$

$H_{2} O + S$

$H_{2} S O_{4} + S$

$H_{2} O + S O_{2}$

In limited supply of oxygen, $H_{2} S$ burns with blue flame and $S$ and $H_{2} O$ are the main products.
$2 H_{2} S + O_{2} ⟶ 2 H_{2} O + 2 S$
In excess of oxygen, $H_{2} S$ gives $S O_{2}$ and water as main product.
