Which full equation has the same net ionic equation as H+(aq)+OH−(aq)→H2O(l)\mathrm{H^{+}(aq)} + \mathrm{OH^{-}(aq)} \rightarrow \mathrm{H_{2}O(l)}H+(aq)+OH−(aq)→H2O(l)?
HCl(aq)+NaOH(aq)→NaCl(aq)+H2O(l)\mathrm{HCl(aq)} + \mathrm{NaOH(aq)} \rightarrow \mathrm{NaCl(aq)} + \mathrm{H_{2}O(l)}HCl(aq)+NaOH(aq)→NaCl(aq)+H2O(l)
HCl(aq)+AgNO3(aq)→AgCl(s)+HNO3(aq)\mathrm{HCl(aq)} + \mathrm{AgNO_{3}(aq)} \rightarrow \mathrm{AgCl(s)} + \mathrm{HNO_{3}(aq)}HCl(aq)+AgNO3(aq)→AgCl(s)+HNO3(aq)
Zn(s)+2HCl(aq)→ZnCl2(aq)+H2(g)\mathrm{Zn(s)} + 2\mathrm{HCl(aq)} \rightarrow \mathrm{ZnCl_{2}(aq)} + \mathrm{H_{2}(g)}Zn(s)+2HCl(aq)→ZnCl2(aq)+H2(g)
CaCO3(s)+2HCl(aq)→CaCl2(aq)+CO2(g)+H2O(l)\mathrm{CaCO_{3}(s)} + 2\mathrm{HCl(aq)} \rightarrow \mathrm{CaCl_{2}(aq)} + \mathrm{CO_{2}(g)} + \mathrm{H_{2}O(l)}CaCO3(s)+2HCl(aq)→CaCl2(aq)+CO2(g)+H2O(l)
