The reaction is $\text{SiO}_2\text{(s)} + \text{Na} _2\text{CO}_3\text{(s)} \xrightarrow{\Delta} \text{Na}_2\text{SiO}_3\text{(s)} + \text{CO} _2\text{(g)}$. Silica displaces the weaker acid (carbonic acid, which decomposes to CO$_2$) from its salt.
SiO$_2$ is reacted with Sodium Carbonate. What is the gas liberated?
