This chemical reaction represents a series of transformations starting with O2 (oxygen) reacting to form H2O (water), which then transforms back into O2. Next, O2 reacts with CaO (calcium oxide) to form CaSO3 (calcium sulfite), which further reacts to form CaCl2 (calcium chloride), and finally, CaCl2 reacts to form CaCO3 (calcium carbonate).
