calculate the coupling constants for jab and jcd using the peak data provided be sure to indicate which spikes in the crowded region near 5.25 ppm correspond to each proton use either arrows or colors to be specific when labeling the spectrum remmeber that cis and trans double bonds have distinct coupling constant ranges g

Less stable  hope this

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

Solubility would be your answer.
