Answer 1

\(2Fe+3Cl_2\rightarrow2FeCl_3\)

\(FeCl_2+2AgNo_3\rightarrow Fe\left(NO_3\right)_2+2AgCl\)

\(CuSO_4+2NaOH\rightarrow Cu\left(OH\right)_2+Na_2SO_4\)

\(K_2O+H_2O\rightarrow2KOH\)

\(2Al\left(OH\right)_3+3H_2SO_4\rightarrow Al_2\left(SO_4\right)_3+6H_2O\)

\(Zn+2HCl\rightarrow ZnCl_2+H_2\)

\(4FeS_2+11O_2\rightarrow2Fe_2O_3+8SO_2\)
