20 ! 1 based on the information here, if 220 grams of the salt kbr are added to 100 ml of water at 100oc, we would label that solution as a) insoluble b) saturated c) supersaturated d) unsaturated

The answer is C: supersaturated

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

No because it not possibly
