State the ionic equation for the reaction when dilute nitric acid is added to aqueous sodium carbonate.

  • A$2\text{HNO}_3(aq) + \text{CO}_3^{2-}(aq) \rightarrow \text{H}_2\text{O}(l) + \text{CO}_2(g) + 2\text{NO}_3^{-}(aq)$
  • B$2\text{H}^+(aq) + \text{CO}_3^{2-}(aq) \rightarrow \text{CO}_2(g) + \text{H}_2\text{O}(l)$
  • C$2\text{HNO}_3(aq) + \text{Na}_2\text{CO}_3(aq) \rightarrow 2\text{NaNO}_3(aq) + \text{CO}_2(g) + \text{H}_2\text{O}(l)$
  • D$2\text{HNO}_3(aq) + \text{CO}_3^{2-}(aq) \rightarrow \text{H}_2\text{O}(l) + \text{CO}_2(g) + 2\text{NO}_2^{-}(aq)$
