Li2CO3 = Li2O + CO2 ↑ the process of dissociation of lithium carbonate occurs under the influence of temperature, the decomposition products are lithium oxide and carbon dioxide.
ZnCO3 = ZnO + CO2 ↑ the process of dissociation of zinc carbonate occurs under the influence of temperature, the decomposition products are zinc oxide and carbon dioxide.
CrCO3 = Cr + CO2 ↑ the process of dissociation of chromium carbonate occurs under the influence of temperature, the decomposition products are chromium and carbon dioxide.
Na2CO3 = Na2O + CO2 ↑ the process of dissociation of sodium carbonate occurs under the influence of temperature, the decomposition products are sodium oxide and carbon dioxide.
Al2 (CO3) = the decomposition of such a substance is not possible, it is insoluble.
CaCO3 = CaO + CO2 ↑ the process of dissociation of calcium carbonate occurs under the influence of temperature, the decomposition products are calcium oxide and carbon dioxide.
