A) \[N{{a}_{2}}C{{O}_{3}}\]
B) \[CuC{{O}_{3}}\]
C) \[A{{g}_{2}}C{{O}_{3}}\]
D) \[{{(N{{H}_{4}})}_{2}}C{{O}_{3}}\]
Correct Answer: D
Solution :
Ammonium carbonate, on heating, decompose into ammonia and carbondioxide, hence leaves no residue. \[{{(N{{H}_{4}})}_{2}}C{{O}_{3}}\xrightarrow{\Delta }2N{{H}_{3}}\uparrow +C{{O}_{2}}\uparrow +{{H}_{2}}O\uparrow \]
