Examine the given Beer's law standard curve for an unknown dye measured in a 1.0 cm cuvette. What is the molar absorptivity (in M^-1cm^–1) of the unknown dye at 542 nm?

Which of the following did you identify correctly

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
