what would be the name for Hsubscript 2 S?

hydrogen sulfide gas? If it is in water solution, it has another name.

what do you mean "if it is in a water solution it has another name"?
You can't mix gas with water.
You can change compounds from solid to liquid to gas, by heating it or cooling it.
Is there another compound used to condense the hydrogen sulfide into a liquid? If so you just add that compound to the name.
If you aren't adding anymore elements to the mixture then the name doesn't change.
State the question you are being asked and I'll help better.
