1. After filtering your final product, you find that your product is still wet, but you proceed to take a melting point anyways. The literature melting point of luminol is 319 °C. What do you expect the melting point of your luminol to be? What would you expect the yield to be? Would it be an accurate yield?
2. While going to conduct the chemiluminescence test, you forgot to dilute Solution A. What do expect the effect of your chemiluminescence would be? Be specific with respect to time and intensity of chemiluminescence (assume that you successfully synthesized luminol).
3. If your reaction proceeded with 82% yield how much product you isolated? Show all work.
Please help me ASAP!

Answer ALL parts a)-e). You are given an experimental procedure in which aniline reacts with acetic anhydride to give acetanilide as shown below. The procedure uses 5.9 g of aniline and 6.3 g of acetic anhydride. aniline, M, 93 acetic anhydride, M, 102 acetanilide, M, 135 Calculate which of the reagents is limiting, and hence determine the maximum possible yield of acetanilide in grams.

Find %yield please the product obtained was 0.0870g
In the hood, place 100 mu L of aniline in a tared 10 times 75 mm (small) test tube. Place the test cube in a small beaker or Erlenmeyer flask to avoid spillage. Stopper the cube with a cork. Now, using a Pasteur pipet, add (with swirling) 0.5 mL of water, followed by three drops of concentrated HCI. Add 10 mg of decolorizing charcoal (we use the pelletized form, called Nonrit^TM) to...
