Why Is HCl a Stronger Acid Than H2S?

[Sir_Viking]

Explain the following observations a) HCl is a stronger acid than H₂S; etc...

I just need to know how to find this out, I read through the chapter but it didn't explain it all that well, and the notes my teacher gave me didn't go over it at all.

You are studying equilibrium of acids or bases. The strength of an acid in this way is how much it dis-associates into ions in solution. A strong acid dissociates completely or nearly completely; a weak acid dissociates not so much. Hydrochloric acid is a strong acid; hydrogen sulfide ( H₂S ) is a weak acid; oxalic acid is somewhere in between.
