Answer:
During burning of incense stick, some pleasant smelling gases are produced (which go into the air) and ash is left behind. We cannot recombine the gases and the ash to get back the original incense stick. So, this is a change which cannot be reversed. Thus, the burning of an incense stick is an irreversible change.
