$\text{Sodium carbonate.........}$

#### Explanation:

The salt derives from $N {a}^{+}$, and $C {O}_{3}^{2 -}$.
$C {O}_{3}^{2 -}$ is called the carbonate ion
You will need 2 sodium ions ($N {a}^{+}$) to even out the charges:

$2 N {a}^{+} + C {O}_{3}^{2 -} \to N {a}_{2} C {O}_{3}$

Sodium hydrogen carbonate or sodium bicarbonate is:

$N {a}^{+} + H C {O}_{3}^{-} \to N a H C {O}_{3}$
