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 sub-levels, number of spots…]

What is the purpose and idea behind the experiment of conducting conductometricic titration of H2(SO4) and Ba(OH)2? what sources of error can be made and how these errors would affect the result?

In the laboratory, a general chemistry student measured the pH of a 0.550 M aqueous solution of formic acid, HCOOH to be 1.987.

Use the information she obtained to determine the K_a for this acid.

K_a(experiment) =

Experiment data taken in a batch reactor predicted the CSTR conversion should be 50%. However, the concentration measured in the actual CSTR was 57%. Suggest a reason for the discrepancy between the predicted and measured conversion.

After the experiment of Aluminum, Copper and Nylon specimens, data shows that the tangent modulus is lower than the Young's modulus.
What does that physically mean?
Are the specimens showing signs of softening or hardening?

what information do you look at to evaluate whether an effect obtained in an experiment is large enough to have practical /clinical significance? also give an example of interpreting practical or clinical significance.

for the experiment of rolling an ordinary pair of dice, find the probability that the sum will be even or a multiple of 6. ( you may want to use a table showing the sum for each of the 36 equally likely outcomes.)

Problem 1 [20 pts]: An experiment consists of tossing a coin 6 times. Let X be the random variable that is the number of heads in the outcome. Find the mean and variance of X.
