A) Na
B) \[N{{a}_{2}}C{{O}_{3}}\]
C) \[NaC{{O}_{3}}\]
D) \[N{{a}_{2}}(HC{{O}_{3}})\]
Correct Answer: B
Solution :
When sodium bicarbonate \[(NaHC{{O}_{3}})\]is heated, sodium carbonate, \[C{{O}_{2}}\] and water are formed. \[2NaHC{{O}_{3}}\xrightarrow{\Delta }\underset{\text{Sodium carbonate}}{\mathop{N{{a}_{2}}C{{O}_{3}}}}\,+C{{O}_{2}}\uparrow +{{H}_{2}}O\]
