Which reaction doesn't get back to reactants ( chemical equilibrium question): 1)NaOH + HCL = NaCl + H2O 2) AgNO3 + BaCl2 = AgCl + Ba(NO3)2 3) 2Cu(NO3)2 = 2 CuO + 4NO2 + O2 4) CO + H2O = CO2 + H2 (closed container)

    Water (H2O) and common Salt (NaCl) when mixed if produced a strong acid and strong base then our lives would be difficult :) what do you think is the ans?

    I think it will be B. Basically, for a reaction to be of a reverse character, there is a need for both reactants and products to be in aqueous states. As for B, a solid AgCl is formed and cannot react with Ba(NO3)2 to go back to the original aqueous reactants.
