For the following questions, provide the best possible solution to solve common mistakes that could occur in the luminol synthesis. If you believe there is no problem, simply indicate so. Assume that all lab equipment (thermometer, heating mantle, etc) are working properly. Briefly explain your answer. The question will receive a zero if no explanation is provided! 1. (2 pts) Sketch the diagram below that would illustrate the set up for the first step of luminol synthesis. Clearly label each...

3. (3 pts) You accidentally add too much hydrazine solution (H2NNH2, 30 ml) to the reaction. How would you correct this mistake? If it was left unfixed, what do you predict the effect on the yield to be? NO2 o NO2 HANNH_HO 220 °C, 3-4 min a.) NaOH/H,O, Na, $,04 -100 °C, 5 min ОН NH -OH NH b.) CH,COOH OH HO (Triethylene glycol - solvent) O 3-nitrophthalic acid (Does NOT chemiluminesce.) 3-nitrophthalhydrazide (Does NOT chemiluminesce.) NH₂ i NH NH...

4. (3 pts) You accidentally add too little hydrazine (H2NNH2, 0.25 mL) to the reaction test tube and the solution is already heating to almost 100 °C. How would you correct this mistake? If left unfixed, what would you expect the effect on the yield to be? 5. (3 pts) You accidentally added half the amount of 3-nitrophthalic acid to the reaction. You have already started filtering the first product. How would you correct this mistake? If left unfixed, what...

2. EXERCISE 8.4 SURPLUS AND DEADWEIGHT LOSs 1. Sketch a diagram to illustrate the competitive market for bread, showing the equilibrium where 5,000 loaves are sold at a price of 2.00. 2. Suppose that the bakeries get together to form a cartel. They agree to raise the price to 2.70, and jointly cut production to supply the number of loaves that consumers demand at that price. Shade the areas on your diagram to show the consumer surplus, producer surplus, and...
