You are given a material to analyze and are told that the
interplanar spacing is
approximately 1 Å. You are trying to decide which x-ray target to
use to characterize this
material: copper or tungsten. Calculate the K emission wavelength
for each material. Which
target should you use and why?
What mass (in g) of iron (Fe, molar mass = 55.85
g∙mol–1) is needed to experimentally produce 50.0 g of
iron(III) oxide (Fe2O3, molar mass = 159.70
g∙mol–1) in excess oxygen if the percent yield is
78.7%?
4Fe(s) +
3O2(g)2Fe2O3(s)
A. 22.2 g
B. 27.5 g
C. 35.0 g
D. 44.4 g
If acidic H2O2 is mixed with Fe^2+, which reaction occurs: the
oxidation of Fe^2+ to Fe^3+ or the reduction of Fe^2+ to Fe? Give
the balanced redox reaction for each possibility and explain your
reason for selecting the reaction which will occur. Assume standard
solution concentrations.
For a) I have:
red: H2O2 + 2H+ + 2e- ---> 2 H2O E=+1.78 V
oxi Fe2+ ----> Fe3+ + e- E=-0.77V
Ecell = 1.01V
I'm stuck on b) but for the explanation I...
What is the process of acquiring white cast Fe, Gray cast Fe,
ductile cast Fe and malleable cast Fe, as well as their carefully
sketch microstructures?
Identify and describe what measurement methods, instruments and
processes may be needed to collect and analyze behavioral data
about emerging leadership trends. Why are these important to
leadership?
Create/draw a clear and organized FLOWCHART for K+, Fe+2 or
Fe+3, Ni+2, Cr+3, NO3- and PO4-3. Discuss observations for any
precipitate/color changes, what you would see if it was or wasn't
there, etc.

Using the IS-LM-FE model for a small open economy, analyze the
effects of a contractionary monetary policy on output and the real
interest rate in the short run and the long run. In each case,
discuss the differences between the classical and the Keynesian
models.
What Statistical Test Should I Use Please indicate the type of test
needed to analyze the data described. Hints: Think about the IV and
DV. How many levels of the IV? Are they repeated measures? Are the
data categorical?
a. z-test
b. One-Sample t-Test
c. Dependent Measures t-test
d. Independent Measures t-test
e. One-way ANOVA
f. Post-hoc tests
g. Between-Subjects Factorial ANOVA
h. Chi-Square test of Independence
