A) \[MgC{{O}_{3}}\]
B) \[~CaC{{O}_{3}}\]
C) \[{{K}_{2}}C{{O}_{3}}\]
D) \[~N{{a}_{2}}C{{O}_{3}}\]
Correct Answer: A
Solution :
Thermal stability order \[{{K}_{2}}C{{O}_{3}}>N{{a}_{2}}C{{O}_{2}}>{{C}_{3}}C{{O}_{3}}>MaCO\] Therefore, \[MgC{{O}_{3}}\]releases \[C{{O}_{2}}\]most easily \[MgC{{O}_{3}}\xrightarrow{\Delta }MgO+C{{O}_{2}}\]
