When a single compound breaks down into two or more compounds or elements in a chemical reaction then it is known as decomposition reaction.
The chemical symbol for sodium carbonate is [tex]Na_2CO_3[/tex].
The decomposition of sodium carbonate is:
[tex]Na_2CO_3\rightarrow Na_2O+ CO_2[/tex]
The decomposition of sodium bicarbonate, [tex]Na_2CO_3[/tex] will result in the formation of sodium oxide, [tex]Na_2O[/tex] and carbon dioxide, [tex]CO_2[/tex].
Hence, carbon dioxide, [tex]CO_2[/tex] will produce with sodium oxide, [tex]Na_2O[/tex] on decomposition of [tex]Na_2CO_3[/tex].
