Calcium carbonate decomposes upon heating, producing …
23/8/2013· Calcium comes from group 2 in the periodic table. The carbonate ions thus coine with an identical nuer of calcium ions. We can visualize the chemical ''formula'' for calcium carbonate as CaCO3. Similarly, Calcium oxide is CaO, and Carbon dioxide is CO2.
Many metal nitrates decompose to form the metal oxide, nasty brown nitrogen dioxide gas (NO 2) and oxygen gas (O 2) when strongly heated. Note: Nitrogen dioxide is more correctly and systematically names as nitrogen(IV) oxide.

Once ignited, calcium metal burns in air to give a mixture of white calcium oxide, CaO, and calcium nitride, Ca 3 N 2. Calcium oxide is more normally made by heating calcium carbonate. Calcium, immediately below magnesium in the periodic table is more reactive with air than magnesium.
