Answer 3

\(Ba+2HCl\rightarrow BaCl_2+H_2\)

\(Na_2O+2HCl\rightarrow2NaCl+H_2O\)

\(Fe+2HCl\rightarrow FeCl_2+H_2\)

\(MgO+2HCl\rightarrow MgCl_2+H_2O\)

\(ZnO+2HCl\rightarrow ZnCl_2+H_2O\)

\(CuO+2HCl\rightarrow CuCl_2+H_2O\)

\(2NaOH+ZnO\rightarrow Na_2ZnO_2+H_2O\)

\(P_2O_5+6NaOH\rightarrow2Na_3PO_4+3H_2O\)

\(Ba+CuSO_4\rightarrow BaSO_4+Cu\)

\(Fe+CuSO_4\rightarrow FeSO_4+Cu\)

\(Ba+2AgNO_3\rightarrow Ba\left(NO_3\right)_2+2Ag\)

\(Fe+2AgNO_3\rightarrow Fe\left(NO_3\right)_2+2Ag\)
