Sodium carbonate and sulfuric acid react to produce carbon dioxide, water and a sodium salt. An incomplete equation for this reaction is shown below. $\text{Na}_2\text{CO}_3 + \text{H}_2\text{SO}_4 \rightarrow \text{CO}_2 + \text{H}_2\text{O} + \dots$ What is the formula of the sodium salt?
- A$\text{Na}_2(\text{SO}_4)_2$
- B$\text{Na}(\text{SO}_4)_2$
- C$\text{Na}_2\text{SO}_4$
- D$\text{NaSO}_4$
