Question 7

Which ionic equation represents a precipitation reaction?

$H+(aq)+OH−(aq)⟶H2O(l)\text{H}^+(aq) + \text{OH}^-(aq) \longrightarrow \text{H}_2\text{O}(l)$

$Ag+(aq)+Cl−(aq)⟶AgCl(s)\text{Ag}^+(aq) + \text{Cl}^-(aq) \longrightarrow \text{AgCl}(s)$

$Zn(s)+Cu2+(aq)⟶Zn2+(aq)+Cu(s)\text{Zn}(s) + \text{Cu}^{2+}(aq) \longrightarrow \text{Zn}^{2+}(aq) + \text{Cu}(s)$

$CO32−(aq)+2H+(aq)⟶CO2(g)+H2O(l)\text{CO}_3^{2-}(aq) + 2\text{H}^+(aq) \longrightarrow \text{CO}_2(g) + \text{H}_2\text{O}(l)$
