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

    A) [tex]BaCO_{3} > SrCO_{3} > CaCO_{3} > MgCO_{3}[/tex]

    B) [tex]MgCO_{3} > CaCO_{3} > SrCO_{3} > BaCO_{3}[/tex]

    C) [tex]CaCO_{3} > MgCO_{3} > BaCO_{3} > SrCO_{3}[/tex]

    D) [tex]SrCO_{3} > BaCO_{3} > CaCO_{3} > MgCO_{3}[/tex]

    Answer:

    Explanation:

    The correct option is A:

    [tex]BaCO_{3} > SrCO_{3} > CaCO_{3} > MgCO_{3}[/tex]

    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 [tex]MgCO_{3}[/tex] to [tex]BaCO_{3}[/tex] ​.  

     

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

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

    Cheers
