When hydrochloric acid is added to iron sulfide, the pungent odour of "rotten eggs" is produced due to the formation of the new substance hydrogen sulfide gas. Katie Harry answered When you mix hydrochloric acid and silver nitrate, there is a chemical change and the overall reaction is that of double displacement. In a physical change, matter changes its appearance (physical properties) but not its composition. Although some may speak this of an example of double displacement reaction, this has no direct relationship with reactivity of hydrogen and silver because there is no transfer of electrons (which occurs in redox reactions). Double Replacement Reaction occurs.. it is a form of a Chemical change.
