To achieve the desired transformation, you will need to perform a series of chemical reactions. First, start by reacting CH4 (methane) with O2 (oxygen) using a spark or heat source to form CO2 (carbon dioxide) and H2O (water). Next, react the CO2 with CaO (calcium oxide) to form CaCO3 (calcium carbonate). Then, add a sufficient amount of H2O to the CaCO3 to form a solution of Ca(HCO3)2 (calcium bicarbonate). After that, add a solution of CaCl2 (calcium chloride) to the Ca(HCO3)2 to produce CaCO (calcium carbonate) and CO2. Finally, heat the CaCO to produce CaO (calcium oxide) and CO2. With these steps, you should be able to achieve the desired transformation of CH4 to CO2 and CaCl2 to CaO. Just be sure to handle all chemicals with care, wear appropriate safety gear, and dispose of waste properly. Good luck!
