<span>K2S(aq) + 2 HBr(aq) = 2 KBr + H2S(g)

potassium sulfide + hydrobromic acid = potassium bromide + hydrogen sulfide

The gas is H2S, hydrogen sulfide

Answer:

The chemical equation of the reaction is given as:

$2HBr(aq)+K_2S(aq)\rightarrow 2KBr(aq)+H_2S(g)$

Explanation:

When aqueous solution of hydrobromic acid combines with aqueous solution of potassium sulfide they give aqueous solution of potassium bromide and hydrogen sulfide gas.

The chemical equation of the reaction is given as:

$2HBr(aq)+K_2S(aq)\rightarrow 2KBr(aq)+H_2S(g)$

According to reaction, 2 moles of hydrobromic acid reacts with 1 mole of potassium sulfide to form 2 moles of potassium iodide and 1 mole of hydrogen sulfide gas.
