    Which is the correct order of ease of carbon dioxide production by heating the group II metal carbonates?​

    A) BaCO_{3} > SrCO_{3} > CaCO_{3} > MgCO_{3}

    B) MgCO_{3} > CaCO_{3} > SrCO_{3} > BaCO_{3}

    C) CaCO_{3} > MgCO_{3} > BaCO_{3} > SrCO_{3}

    D) SrCO_{3} > BaCO_{3} > CaCO_{3} > MgCO_{3}

    Answer:

    Explanation:

    The correct option is A:

    BaCO_{3} > SrCO_{3} > CaCO_{3} > MgCO_{3}

    On the periodic table, carbonates required stronger heating as one does down the groupings in order for them to decompose. The implication is that  the stability of compounds will increase from MgCO_{3} to BaCO_{3} ​.  

     

    So the carbonates will be stable according to the following order:

    BaCO_{3} > SrCO_{3} > CaCO_{3} > MgCO_{3}, thus making B the correct answer.

    Cheers
