Answer #1

We know that,

The Evans method uses difference in the NMR chemical shift in a solvent caused by the presence of a paramagnetic species. It can be used to determine the magnetic moment of the paramagnetic and the number of unpaired electrons present.

Nowadays NMR is the most promising technique and so we believe it has the least error. So the values we get from this method is much acceptable. Whereas in balance method we have to take the weight of the substance,

Mn(salen)(AcAc) was actually a failed experiment by design. You were not supposed to synthesize this compound. You should remember that Mn(salpn)(AcAc) was readily synthesized in week 3 as crystalline materials. In your discussion section, explain why we cannot make Mn(salen)(AcAc)? (hint: salpn has a 3-carbon chain between two nitrogen donors, which make it more flexible).

Design an experiment in which two factors are to be investigated, one at two levels and one at three levels. The experiment must run in blocks, with no more than four test runs per block. Up to 20 blocks can be used in the experiment. ***If you can explain the two factors, one at two levels and one at three levels a little more, because i think that is what has me more confused***

CHEM 114 ‐ Lab Experiment 7 Equilibrium I – Determination of an Equilibrium Constant 3. In this lab, the measurement wavelength on the colorimeter was set at 470 nm.  This measurement wavelength was the best choice available on the colorimeter but it was not the best chemical choice for measuring the absorbance of FeSCN2+.    a. In terms of instrument sensitivity, explain why the choice of wavelength on the colorimeter is important.   b. Since the wavelength setting was not the ideal wavelength...

The opening and closing balances are the same regardless of which method you are using. The cash flow statement is prepared after the books have been closed. If there are erroneous postings, then the closing balances will be affected as well, not just individual line items that impact cash. Also, think of the journal entry method used in the direct method in this text. Aren't we using ending ledger balances to determine cash flows? For example, if Sales =$500, and...

Q1. An experiment studied the role of the complement system for clearance of bacteria from the blood of mice. Two types of mice were used in the study: C1q-knockout mice and wild type mice. The mice were infected with either antibody-coated or un-coated bacteria (in a fully factorial design, i.e, both mouse genotypes were exposed to both types of bacteria), and the clearance rate was measured during two hours after bacterial administration. Explain the protecting mechanisms (not only those involving...

3. When using the slope-intercept form to graph linear inequalities, how do you know which side of the line to shade on? 4. What is an alternative method that can be use to indicate that the appropriate regions are shaded correctly? Be sure to explain how you would know this method indicates the shading is correct or incorrect. 5. When graphing the shaded regions for a system of linear inequalities, what indicates the solution set of the system?
