Can someone please answer these questions for me?

1. (3) The FeSCN " complex appears red-orange because it absorbs what color light? 2. (3) What is the name of the scientific law obeyed in this experiment that relates the concentration of a colored solution to its absorbance value? 3. (3) For Part A: Should your K values agree with one another? Why or why not? 4. (6) For Part B: a. Which of the three species in the equilibrium mixture absorbs visible light? b. Based on your response above, describe the change in color intensity and absorbance when Fe3 is added to the equilibrium mixture. In terms of LeChtlier's principle, why did this change occur? c. Based on your response above, describe the change in color intensity and absorbance when SCN was added to the equilibrium mixture. In terms of LeChtlier's principle, why did this change occur
