Question

What else is produced when sodium carbonate decomposes? Na2CO3 Na2O +

Answer 1

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 $Na_2CO_3$.

Answer 2

Na2CO3 Na2O +CO2   CO2 is the answer
