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 \(Na_2CO_3\).
The decomposition of sodium carbonate is:
\(Na_2CO_3\rightarrow Na_2O+ CO_2\)
The decomposition of sodium bicarbonate, \(Na_2CO_3\) will result in the formation of sodium oxide, \(Na_2O\) and carbon dioxide, \(CO_2\).
Hence, carbon dioxide, \(CO_2\) will produce with sodium oxide, \(Na_2O\) on decomposition of \(Na_2CO_3\).
