Question

write a the chemical equation for the formation reaction of H2S gas

Answer 1

FeS + 2 HCl → FeCl2 + H2S

Answer 2

The Indirect Method. In many cases, enthalpies of formation cannot be determined by a direct calorimetry experiment. For example, the formation reaction of hydrogen sulfide (H2S) will not go cleanly in a calorimeter, and many other compounds besides H2S are formed when sulfur and hydrogen react. In cases like these, a calculational method can used to determine .

S(s) + H2(g) H2S(g)
