Mass spectroscopy: parent ion. appearance of m and m+2 peaks of similar sizes for ions that contain Br. The mass spectra below are those of p-bromotoluene, 1-bromo-2-phenylethane. and 1-chloro-2-phenylethane. Identify each spectrum with the appropriate compound, and explain how you decided their identities. Note particularly the characteristics of the peaks for ions containing bromine (isotope peaks).
Number 2. Thank you 2. (2pt) Why do atomic emission spectra come in the form of lines instead of broad bands that span whole regions of the electromagnetic spectrum? Atoms have quantized energy Tevels, they react to principal quantum numbers n=1,2,..
3) The IR spectrum of [(-C5H5)Fe(CO)2]2 shows two bands in two different areas of the (CO) region - close to 1800 cm-1 and close to 2000 cm-1 . Why is this so? (A general answer will suffice; it is not necessary to assign all the bands in the IR spectrum of the dimer). 44 2) On the following page you will find illustrations of the v(CO) region of the IR spectra of (n-C5H5)Fe(CO)21 and [(1-C5H5)Fe(CO) 2]2 obtained using cyclohexane solutions...
Questions(Answer on an attached sheet of paper and turn in with the report) 1. Why do metals give off different colors in a flame test? 2. You spray paint the letters SPECTROSCOPY in yellow paint on snow. After a while the sun comes out and the snow under the yellow paint melts, leaving the letters in the word SPECTROSCOPY intact. Why did the snow under (rather than around) the yellow paint melt? 3. The graph below shows the absorption spectra...
account for the use of the different solvents in the purification of 2. hint. think about how solvent polarity and solubility are related flask In a 100-ml round bottom three-necked flask with 14/20 joints is placed 1.4 g of boric acid and 3 ml. of triethanolamine (p1.124 g ml.") together with a magnetic stirring bar. Toluene (40 ml) is then added and the two side necks are closed with 14/20 glass stoppers (or rubber septa). In the central neck is...
Prelab questions 1,2, and 3 and Part E questions Also, write a flowchart of the experiments process in each part. EXPERIMENT 3 DETERMINATION OF Δo The d orbitals of a metal ion in an octahedral ligand or crystal field are split into a higher energyset (eg) and a lower energy set (t2g) as shown in the following energy level diagram. 11 The energy difference between the upper and lower energy levels is Δo, the octahedral crystal field splitting. The degree...
Please analyse the case study and answer 2 following questions. Thanks! a) Explain why Myanmar should/should not use protectionist policies b) Present a country that also has applied IIP in the past to evaluate its costs and benefits Myanmar is working hard to make the difficult economic transition from its current status as a Least Developed Country to its once-held spot as one of the most developed Asian economies. Urged on by many international and domestic experts, sweeping liberalisation reforms...
Below is the information: It is important to understand the different leadership styles employed by nursing leaders in healthcare organizations and to understand their significance on nursing practice and patient outcomes, for better or for worse. Objective: Read the articles from Nursing Standard (PDF) and Bradley University (PDF). In -250 words, formulate an opinion on the following: 1. Reflect on an occasion where you experienced ineffective leadership (doesn't have to be in the hospital). What behaviors did they display? What...
