    Decomposition of a Carbonate - sartep

    Carbonates are compounds formed between a metal and the carbonate ion, (CO 3) 2-. When a carbonate decomposes, a metal oxide and carbon dioxide gas are produced. The general pattern of a decomposition of a carbonate reaction is: MCO 3--> MO + CO 2 (M is used to represent the metal. CO 3 is carbonate.) Look at the example below. Example #1:
