- complete the table Procedure Preheat the hotplate stirrer with an aluminum block to 45–50 °C (do not exceed 55 °C). To a clean 5-mL conical vial equipped with a Teflon-coated magnetic stir vane, add 4- bromo-nitrobenzene (152 mg, 0.750 mmol, 1 equiv) and THF (150 μL). Cap the vial and stir the mixture at 45–50 °C for about 30 s to partially dissolve the substrate; don’t stir too fast to avoid splashing the contents on the walls of the vial. Add ammonium chloride (120 mg, 2.2 mmol, 3 equiv), carbonyl iron powder (CIP; 210 mg, 3.80 mmol, 5 equiv), the solution of TPGS-750-M (2% in water, 1.5 mL), and 1 drop of concentrated HCl. Cap the vial and place it on the hot plate stirrer, stirring at 45–50 °C. While the reaction mixture is stirring, prepare an approximate 2% solution of the reactant in DCM (1 sample per 3–4 students) by dissolving 10–15 mg of 4-bromo-nitrobenzene in 0.5 mL of methylene chloride. Prepare the solvent mixture for the mobile phase (25% ethyl…1 Report on how to decrease the droplet evaporation time for liquidfuel combustion.1.

- Make a schematic diagram for the procedure below: A. Constant weighing of the crucibles Bring two porcelain crucibles to constant weight by heating to redness for 15 min over a burner (not including the cover; see Figure 1 for heating set-up). Cool the crucibles briefly on clean Al foil-covered wire gauze at room temperature for 5 min and into the desiccator for 25 minutes. Weigh each crucible accurately on an analytical balance. Repeat procedure a and b until two successive weights agree within ± 0.3 mg, be sure that all oxidizable substances on the entire surface of each crucible have been burned off.Draw and label a moisture sorption isotherm for any product of your choice at different temperature conditions of 0ºC, 25ºC, and 45ºC.
