Определи вещества \(\mathbf{X}\) и \(\mathbf{Y}\) в схеме превращений

\(\mathbf{CaCl\_2 (+X) \to}\) \(\mathbf{CaCO\_3 (+Y) \to}\) \(\mathbf{Ca(NO\_3)\_2}\)

• \(\mathrm{X – K\_2CO\_3}\) , \(\mathrm{Y – HNO\_3}\)
• \(\mathrm{X – CO\_2}\) , \(\mathrm{Y – NO\_2}\)
• \(\mathrm{X – NaHCO\_3}\) , \(\mathrm{Y – Ba(NO\_3)\_2}\)
• \(\mathrm{X – (NH\_4)\_2CO\_3}\) , \(\mathrm{Y – AgNO\_3}\)
