For each of the following reactions, write the appropriate equilibrium equation. (Equilibrium expressions take the general form: Keq = [C]c / [A]a . [B]b. Subscripts and superscripts that include letters must be enclosed in braces {}.) (a) CH3COOH(aq) equilibrium reaction arrow CH3COO−(aq) + H +(aq)

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
