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.

Blood typing_ how do you find out to which blood group someone belong?
This is experiment in immunology lab
I want method, results and discussion
Of detect ( A and B) blood

" ion chromatography " is a nice self -contained experiment . 1- how do suppressor column work ?2- discuss some applications of this technique ? 3) why analyze soils with ion chromatography?
