Experiment: The Paramagnetic Complex Mn(acac)3
I)
Which method, Magnetic Susceptibility Using Evans' Method or Magnetic Susceptibility Using a Magnetic Susceptibility Balance, do you think has more error? Explain.
Homework Answers
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***

The opening and closing balances are the same regardless of

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,

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

the experiment. In your answer, make a connection to the method of
electrostatically influencing scale readings studied. Explain the
similarities and differences.
