AIM: To carry out a lab experiment to decompose a carbonate using heat, also to carry out appropriate tests for the formation of products as a result of this decomposition.
DISSCUSION: Carbonates are decomposed by heat into the corresponding oxides and carbon dioxide. The temperature of decomposition depends upon the activity of the metal; that is to say, the more active the metal, the more stable is the carbonate. Thus, the carbonates of sodium and …

…also called Mississippi Valley-type deposits, since that part of North America has many of them. The deposits are generally believed to be formed when mineral-laden fluids travel through fractures or pore spaces in the rock. Chemical conditions in the carbonate rocks cause metals to precipitate from the fluids, to be deposited on fractures and in openings in the rock.
CONCLUSION: we saw that Carbonates are decomposed by heat into the corresponding oxides and carbon dioxide.
