Preparation of salts — practice question

Some details about silver compounds are given in the table. Which equation represents a reaction that cannot be used to prepare a silver salt?

  • A$\text{AgNO}_3\text{(aq)} + \text{HCl}\text{(aq)} \rightarrow \text{AgCl(s)} + \text{HNO}_3\text{(aq)}$
  • B$\text{Ag}_2\text{O(s)} + 2\text{HNO}_3\text{(aq)} \rightarrow 2\text{AgNO}_3\text{(aq)} + \text{H}_2\text{O(l)}$
  • C$\text{Ag}_2\text{CO}_3\text{(s)} + 2\text{HNO}_3\text{(aq)} \rightarrow 2\text{AgNO}_3\text{(aq)} + \text{H}_2\text{O(l)} + \text{CO}_2\text{(g)}$
  • D$2\text{Ag(s)} + 2\text{HCl}\text{(aq)} \rightarrow 2\text{AgCl(s)} + \text{H}_2\text{(g)}$
