It looks like you're trying to show a reaction pathway starting with Ca (calcium) and ending with CaCl2 (calcium chloride). Here is the correct reaction pathway:
Ca → CaH2 → CaO → Ca(OH)2 → CaCO3 → Ca(NO3)2 → Ca(NO2)2 → CaCl2
The pathway you provided has incorrect order and some of the compounds are not in the correct chemical compositions. Let me know if you would like more information or assistance with this reaction pathway.
