Find the current density necessary to float a copper wire in Earth’s magnetic field. Assume the experiment to be done at the Earth’s magnetic equator in a field of 10?4 T. Use nominal density of copper in g/cm^3.

Describe an experiment to examine if cells in culture are undergoing apoptosis. You should include a microscopy method as well as a molecular/biochemical method, and describe expected results for each, with reference to the cellular events known to occur during apoptosis.

For a Differential Scanning Calorimetry Experiment,

The samples are contained in aluminum pans with crimped-on covers. The instrument is stationary during operation, so samples placed in open pans would not spill. Why do you think the covers are needed?

Cu in [Cu(CN)4]2- and [Cu(NH3)4]2+ has d9 electron configuration ,so the geometry should be tetrahedral but the experiment Show that these two ions have square planar geometry.Please explain this statement.

Please answer the following questions:

1. What is a Binomial experiment?
2. What are the expected value and the variance of the Binomial distribution?
3. List the properties of the Normal distribution.
4. What are the two parameters defining the Normal distribution?
5. What is Standard Normal distribution?

CHEM 114 ‐ Lab Experiment 8 Equilibrium II – Le Chatelier’s Principle

2. There is chemical waste that must be disposed of properly in this lab.  Identify which wastes are highly hazardous and explain why they must be properly discarded.

In a student lab experiment, 4.8 MeVMeV alpha particles from the decay of 210Po210Po are directed at a piece of thin platinum foil.

If an alpha particle is directed straight toward the nucleus of a platinum atom, what is the distance of closest approach?

During a Structure and Solubility experiment how do you distinguish between the following:

a.) butane and 2-chlorobutane

b.)butane and 1-butanol

c.)1-butanol and 2-butanol

d.)1-butanol and butanoic acid

In a young's double slit experiment

a) There is no diffraction

b) Diffraction is so small it is not easily seen

c) Diffraction is readily apparent in the interference pattern

d) Diffraction disappears when the slit separation is integer times the slit width

What is the purpose of the experiements determining the dissociation constant of a weak acid using ph measurement and monitoring acid-base titrations with a ph meter? We combined both experiements together into one, just not understand the purpose of the experiment.
