Lab: 5 Experiment:13 Pre-Lab The purpose of this experiment is to observe an equilibrium reaction counteracting changes to it’s system all in accordance to Le Chatelier’s principle. An equilibrium reaction can be pushed toward products or reactant based on changes in temperature or concentration. The reversibility of reaction will also be looked at. Pre-Lab questions 1. The concentrations of products and concentrations of reactants remain constant but both reactions

Experiment #9 – Identification of Aldehydes and Ketones Introduction Aldehydes and ketones share the carbonyl functional group which features carbon doubly bonded to oxygen. In the case of ketones there are two carbon atoms bonded to the carbonyl carbon and no hydrogens. In the case of aldehydes there is at least one hydrogen bonded to the carbonyl carbon; the other attachment may be to a carbon or a hydrogen. In all cases the carbon(s) that are attached to the carbonyl group may be aliphatic (not

CASE STUDY 01 (POSTPARTUM) Assessment A 1‚000 ml bag of Lactated Ringer’s solution containing 10 units of Pitocin (oxytocin) is infusing via an 18 g peripheral IV in the left forearm at 125 ml per hour‚ with 300 ml remaining in the bag. The IV is patent‚ without redness or swelling‚ and can be discontinued when this bag’s infusion is complete. 1. Prior to discontinuing the IV Pitocin (oxytocin)‚ which assessment is most important for the nurse to obtain? [pic]A) Vital signs. [pic]B)

glycol‚ and ~2.50 ppm is DMSO.6 The 1H NMR of the intermediate shows a shielded proton peak in the 0.9-1.7 ppm region with an integration of 3 protons as expected of the methyl group furthest away from the electron withdrawing oxygens (Figure 4). The second most shielded peak also has an integration of 3‚ and would be the methyl group attached to the ketal group. The subsequent C and E peaks have the correct integration and splitting pattern for their appropriate locations as depicted in Figure 4

A. Goal and Purpose: Session 1: In this lab‚ we will achieve a simple Friedel-Crafts alkylation of anthracene. The choice of anthracene as an aromatic substrate stems from two considerations. First‚ there is a question of regioselectivity. Second‚ anthracene and its derivatives are highly visible under UV light. Session 2: In this lab‚ we will complete a partial conversion of 9-acetylanthracene using m-chloroperoxybenzoic acid (mCPBA). We will also determine by NMR‚ the regiochemistry of the

The tests performed to identify the unknown organism included Gram Staining‚ Fluid thioglycollate/aero-tolerance test‚ Methyl Red-Vogues Proskauer‚ SIM test‚ Lysine Decarboxylase test‚ Lactose Fermentation test‚ Simmons Citrate test‚ and TSI test. The Gram staining technique showed that the organism was Gram negative and bacilli shaped. The fluid thioglycollate test showed
