Identify the products when solid calcium carbonate \(\ce{(CaCO3)}\) reacts with aqueous nitric acid \(\ce{(HNO3)}\) and write the balanced chemical equation for the reaction.   (3 marks)

Show Answers Only

\(\ce{CaCO3_{(s)} + 2HNO3_{(aq)} \rightarrow H2O_{(l)} + CO2_{(g)} + Ca(NO3)2_{(aq)}}\)

Show Worked Solution
  • Solid calcium carbonate and nitric acid produce: \(\ce{H2O(l),\ CO2(g), Ca(NO3)2(aq)} \).
  • Balanced equation:
  •    \(\ce{CaCO3(s) + 2HNO3(aq) \rightarrow H2O(l) + CO2(g) + Ca(NO3)2(aq)}\)
