Given are:
1) CuSO4 + BaCl2 ---> BaSO4 + CuCl2
2) <span>Pb(NO3)2 + 2NaCl ---> PbCl2 + 2NaNO3
3) </span><span>N2 + 3H2---> 2NH3
4)</span><span>K2SO4 + BaCl2---> BaSO4 + 2KCl
Among the 4 reactions above, the only oxidation - reduction reaction is number 3:
N2 + 3H2 ----> 2NH3
since the oxidation numbers of N and H decreased and increased, respectively making the reaction RedOx. </span>
