Use the data in appendix l to calculate equilibrium constants for the following reactions. assume 298.15 k if no temperature is given. (a) agcl(s) ⇌ ag +(aq) + cl−(aq) (b) cds(s) ⇌ cd2+(aq) + s 2−(aq) at 377 k (c) hg2+(aq) + 4br−(aq) ⇌ [hgbr4 ] 2−(aq) (d) h2 o(l) ⇌ h +(aq) + oh−(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
