Most likely it is Sulfur
The Properties of sulfur are:
Sulfur is not water soluble but is soluble in carbon disulphide.
Sulfur is a yellow powdery substance.
Sulfur will in the presence of oxygen and heat form sulfur dioxide which is a colorless gas.
The reaction is as thus:

SO2 + H2O -----------> H2SO3
