Want this question answered?
2HCl + Na2S ---> 2NaCl + H2S
when few pieces of marble are added to HCl then carbon dioxide is released.............
when aluminium is added to dil. hcl it forms aluminium chloride and hydrogen gas. 4 Al + +6 HCL=2 Al2CO3 + 3 H2
When zinc granules are reacted with dilute HCl (hydrochloric acid), zinc chloride i.e. ZnCl2 is formed along with the evolution of hydrogen gas H2.
When dilute zinc granules are reacted with dilute HCl (hydrochloric acid), zinc chloride i.e. ZnCl2 is formed along with the evolution of hydrogen gas H2. the presence of hydrogen gas can be tested by bringing a naked flame to the mouth of the test tube. Hydrogen gas burns with a pop sound.

Volcanoes release H2S, HCl, SO2, CO2, etc.
The hydrogen chloride: HCl.

This question may be about preparing H2S (or maybe hydrogen) with Kipp's apparatus.

NH3 + HCl ----> NH4Cl
So2 + h20

Burning of H2S produce SO2 and water.SO2 is the toxic gas.
H2S do not have bleaching properties.So it do not discolor
