Consider the chemical equilibrium of the reaction. agcl(s) ag+(aq) + cl–(aq) what will happen to the chemical equilibrium if agno3 is added? a there is no shift in the chemical equilibrium of the system. b the chemical equilibrium of the system shifts to the right. c the chemical equilibrium of the system shifts to the left. d the chemical equilibrium of the system is destroyed.

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃  → 3 nicl₂ + 2 albarium and copper bromideba + cubr  →  no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al  → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn  → znso₄ + na

The correct answer is "hydrogen".
