Thanks again for your help

H 2 S + (CH 3 COO) 2 Pb → 2 CH 3 COOH + PbS↓

that is OK?

H2S + (CH3COO)2Pb → 2CH4COO + PbS↓

Reaction on lead acetate paper that turns black by PbS.

It's OK?
H2S + (CH3COO)2Pb → 2CH3COO + PbS↓

Thank you very much!

Are the following description and drawing correct?


Reaction on wet indicator paper
H2S + H2O = HS + H3O

Observations:
There is gas coming out of the test tube with a characteristic smell.
Universal test strip turns red when wet.

Conclusions:
The gas that evolves is hydrogen sulfide

is this the correct form of the equation ?

HCl + HS(-) + H3O(+) -> Cl(-) + H3O(+) + H2S↑

HCl + HS(-) + H3O(+) -> Cl(-) + H2S(-) + H3O(+)

dissociation equation H2S + H2O -> H3O(+) + HS(-)

aqueous solution of H2S:
H2S + H2O → H2SO4


2HCl + H2SO4 → Cl2 + SO2 + 2H2O

Are such equations correct?

Please help.
How to present the influence of HCl on an aqueous solution of H2S?
