    1. Al2(CO3)3--->

    Carbonate (CO3-2) ion mostly decomposes to carbon dioxide.

    As you can see in the decomposition of sodium carbonate i.e. Na2CO3 -> Na2O + CO2

    In decomposition reaction of carbonate ion; the oxidation number of carbon atom in carbonate ion and carbon dioxide are the ...
