Alcohol Acetic Anhydride Concentrated H2SO4 Saturated NaHCO3 NaCl solution Reflux Setup: The reflux setup contains a condensing system at a 90-degree angle with the flasks that prevents the solvent from evaporating but at the same time maintaining the temperature of the solvent. The 90-degree angle allows condensed solvent to go back to the reaction pot. PROCEDURE Two dry test tubes labelled A and B containing the required 2.5 mL isoamyl alcohol and 2.6 mL acetic anhydride respectively

acetic anhydride and ferrocene (once applying heat). During column chromatography‚ a solution is passed through a filtration system of silica‚ sand‚ and cotton. This creates colored or colorless bands‚ dependent on the type of chemical compound‚ and is comparable to a reverse TLC test. The differences in polarity pull down the compounds at different rates‚ allowing for the separation. Experimental: Dry‚ sublimed ferrocene (93 mg) was added to a reaction tube. Later‚ 0.35 mL of acetic anhydride and

Sarah‚ While reading your scenario‚ I could feel my heartrate increase. I can clearly recall how anxiety inducing situations like this could be when I was a new nurse. If I were the new nurse in this scenario‚ I hope that I would choose the third option. My progression through the steps in the Ethical Model for Ethical Decision Making proposed by McGonigle‚ Mastrian‚ and Farcus (2018‚ p. 89-91) are as follows: 1. Examine the ethical dilemma.
