. How can you calculate the concentration of a solution with UV-visible spectroscopy if you do not know the molar absorption? A. Add an internal standard. B. Use Beer's Law anyway. C. Add blue dye to the sample. D. Calculate the rate constant. E. Create a calibration curve.

Part A Mark with the green check to indicate that the given direction of electron flow in the following set of molecules using curved arrows notation is correct and with the red X label to indicate when incorrect. Drag the appropriate labels to their respective targets. ► View Available Hint(s) X X X H₂C X CH₂ H₂C Reset Help You labeled 2 of 7 targets incorrectly. Electrons can only be shown to migrate if there is an atomic p orbital to move them to. Moving a lone pair electrons to form a new π bond can only occur if the atom accepting

Create a calibration curve for the following 4 M concentrations. (0.16 M, 0.080 M, 0.040 M, and 0.016 M.) The data is in the attached image. Note* only use the absorbance points from the highlighted (highlighted in blue) column. It is the column with an absorbance of 442.6.
