    A)  \[N{{a}_{2}}C{{O}_{3}}\]        

    B)  \[{{K}_{2}}C{{O}_{3}}\]

    C)  \[L{{i}_{2}}C{{O}_{3}}\]         

    D)  \[R{{b}_{2}}C{{O}_{3}}\]

    Correct Answer: C

    Solution :

    Lithium carbonate decomposes readily at low temperature.       \[L{{i}_{2}}C{{O}_{3}}\xrightarrow{\Delta }L{{i}_{2}}O+C{{O}_{2}}\]
