i know this may be, probably a preposterous question you've come across here, but i'm just curious to know, when we heat MgCl2, why doesn't it give Mg and Chlorine (MgCl2 ---> Mg + Cl2) like when we heat MgCO3 it gives us MgO + CO2 so why is this not the case for MgCl2 too?

Due to differences in ionic bond strength.

Cl(-) ions smaller than CO3(2-) ions so stronger electrostatic attraction to the Mg2+ cation. So MgCl2 has higher bond dissociation enthalpy.

Could be completely wrong though, haven't done Chemistry in a while
