\(AgNO_3+HCl\rightarrow AgCl\downarrow+HNO_3\)	\(Ag^++Cl^-\rightarrow AgCl\downarrow\)
\(Na_2SO_4+Ba\left(OH\right)_2\rightarrow BaSO_4\downarrow+2NaOH\)	\(SO_4^{2-}+Ba^{2+}\rightarrow BaSO_4\downarrow\)
\(2NaOH+H_2SO_4\rightarrow Na_2SO_4+2H_2O\)	\(OH^-+H^+\rightarrow H_2O\)
\(KHCO_3+HCl\rightarrow KCl+CO_2\uparrow+H_2O\)	\(HCO_3^-+H^+\rightarrow CO_2\uparrow+H_2O\)
\(FeS+2HCl\rightarrow FeCl_2+H_2S\uparrow\)	\(S^{2-}+2H^+\rightarrow H_2S\uparrow\)
\(Na_2SO_4+HCl\rightarrow\left(\times\right)\)
\(KOH+NH_4Cl\rightarrow KCl+NH_3\uparrow+H_2O\)	\(OH^-+NH_4^+\rightarrow NH_3\uparrow+H_2O\)
\(BaCO_3+H_2SO_4\rightarrow BaSO_4\downarrow+CO_2\uparrow+H_2O\)	\(Ba^{2+}+SO_4^{2-}\rightarrow BaSO_4\downarrow\\ CO_3^{2-}+2H^+\rightarrow CO_2\uparrow+H_2O\)
