9b. The complex ion Cr(CNANO.)HoONH,] can exhibit chiral properties. There are actually two possible tric forms for this cation; what are they? Then, draw two non-superimposable isomers for each...
9a The Ir(en), 3 cation can exhibit chiral properties. Draw the two non-superimposable isomers for this cation. en--NH NH2-
The complex [Co(NEt3)4(NCS)cl] can form cis and trans isomers and can also exhibit linkage isomerism. Draw both cis and trans forms and show how the linkage isomerism arises.
1. Two types of isomerism are possible for the six-coordinate complex Cr(NO2)2.6H2O. Identify all isomers. (10 Points) 2. The two square-planar isomers of [PtBrCI(PR3)2] (where PR, is a trialkylphosphene) have different 31P-NMR spectra as shown below. For this exercise, we ignore the coupling to 195Pt (I=1/2 at 33% abundance). One isomer (A) shows a single 31P resonance; the other (B) shows two 31P resonances, each of which is split into a doublet by the second 31P nucleus. Which isomer is...
A rigid container initially contains only 0.25 mol of NH3 (g) in a 5.0 L volume. We introduce 0.20 mol of HCI (g) at 25 °C. a. Write the chemical equation for this reaction assuming that it forms one product. b. Calculate the final pressure in the container after the reaction in a. is complete If some of this product were added to water, what would happen to the pH of solution relative to pure water? c. Instead of the...
19-26 thanks! 19-29* PART 3: 2,3-BUTANEDIOL CH-CH(OH)-CH(OH)-CH, mirror images, not superimposable Build as many models of 2,3-butanediol as you can. First, attach two carbons with a single bond. To each carbon add one carbon, one hydrogen, and one oxygen. To complete the structure, Ti the remaining hydrogen atoms. Remember, a model is not different if it is completely superimposable on one already constructed! 13. How many stereochemically different models are possible for 2,3-butanediol? 14. What characteristic does one of these...

What are the instruments that have been utilized for the review article discussions? ` 1. Introduction In recent years, nanoclays have been the object of particular interest for many scientists and researchers in chemistry, physics, engineering and biology due to their excellent properties as well as their sustain- ability [1-3]. For instance, they represent the starting point to the de velopment of smart materials for drug delivery (4-9), food packaging [10-12), environmental remediation and wastewater treatment [13], cultural heritage [14–17and...
1. According to the paper, what does lactate dehydrogenase (LDH) do and what does it allow to happen within the myofiber? (5 points) 2. According to the paper, what is the major disadvantage of relying on glycolysis during high-intensity exercise? (5 points) 3. Using Figure 1 in the paper, briefly describe the different sources of ATP production at 50% versus 90% AND explain whether you believe this depiction of ATP production applies to a Type IIX myofiber in a human....
10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
