How could an experiment such as that performed by Stern and
Gerlach be used to determine the total angular momentum quantum
number of the ground state of a given atom or ion? [magnetic

A) David, an undergraduate research assistant in our lab,
performed Western Blotting experiment and he used anti- Z protein
polyclonal antibody raised in rabbit as a primary antibody. As a
secondary antibody, he used anti-mouse HRP labeled antibody. Could
you please tell him what is wrong with this experiment?
B) David, an undergraduate intern in our lab, forget to block
the blot with BSA and continue to the antibody hybridization steps
and finally developed his blot. Could you please describe...

I recently performed a lab on Chemical Equilibrium.
Here is some background on the experiment:
-We made a stock solution by combining Fe(NO3)3 and NH4SCN. This
made a blood red solution. Then, we added different reagents to see
the change of color and the shift of equilibrium.
I'm being asked the following question: Based on the color of
solutions reported, determine the direction of the reaction's:
Fe^3+(aq)+SCN^- --> [FeSCN]^2+(aq) equilibrium shift upon each
addition of each reagent investigated and write...

Design an experiment that you could perform in our lab to
determine the coefficient of kinetic friction and static friction
and to compare the coefficient of kinetic friction and static
friction. A good design should include details of the materials and
equipment needs, the experimental procedure, including precautions,
the types of data you will collect, how the data will be
represented and analyzed, and how you will determine the accuracy
of your experimental result(s).

2. An experiment was conducted to determine if a drug could be
used as a treatment for the eating disorder anorexia. The test
subjects were women being treated for anorexia. A group of 50
patients received the drug, and after a year, 39 were deemed
healthy. Construct a 99% confidence interval for the true proportion
of patients who would be deemed healthy after receiving the drug
for a year.

. An experiment was performed on a certain metal to determine if
the strength is a function of heating time (hours). Results based
on 20 metal sheets are given below. Use the simple linear
regression model.
∑X = 40
∑X2 = 200
∑Y = 80
∑Y2 = 1120
∑XY = 460
Find the estimated y intercept and slope and write the equation of
the least squares regression line. Estimate Y when X is equal to 3
hours. Also determine the...
