2HCl + Na2S ---> 2NaCl + H2S
Na2S + 2HCl = 2NaCl + H2S (smelly toxic gas) Sodium sulphide + hydrochloric acid => Salt (Sodium chloride) and Hydrogen sulphide

when few pieces of marble are added to HCl then carbon dioxide is released.............
Hydrochloric acid means the 36% solution (maximum) of HCl gas in water, when chlorine is added to this solution a small amount of HOCl is formed along with HCl, it is a useless reaction.
Hydrogen gas and Zinc Chloride
Na2S + 2HCl = 2NaCl + H2S (smelly toxic gas) Sodium sulphide + hydrochloric acid => Salt (Sodium chloride) and Hydrogen sulphide
no

Hydrogen gas and Zinc Chloride
when aluminium is added to dil. hcl it forms aluminium chloride and hydrogen gas. 4 Al + +6 HCL=2 Al2CO3 + 3 H2
h2
It may be white solid Ammonium chloride NH4Cl, formed by Acidic gas HCl and Basic gas NH3.
Yes. MgCl2 is formed with the evolution of H2 gas
Yes, aluminum chloride and hydrogen gas formed
For each mole of hydrogen gas (H2) reacting with chlorine gas (Cl2), you will get 2 moles of HCl. H2 + Cl2 = 2 HCl
