1.Prialt is a medication, derived from snake venom, that can be
administered for relief from chronic pain. A patient has been prescribed
a dose of 3.9 micrograms per day. A nurse accidentally administers a
dosage of 3.9 ng/hr over a period of 11.0 hours.
1. Calculate the amount of Prialt, in micrograms, that this patient
received.
2. Write out the work for this calculation on a piece of paper.
3. Also on the piece of paper, describe what you think is likely to
happen to the patient as the result of this dosage
2. use molecular-level drawings to illustrate and explain the difference
between an mixture of hydrogen and oxygen and a compound made
from hydrogen and oxygen. Use labels as needed to make your
drawings clear.
3 Monicaium (Q) is an element in Group 5A. It has an electronegativity
of 2.3. Its molar mass is 21.55 g/mol. Draw Lewis structures for
QH3 and Q2H2 and use them to answer the following questions in your
video.
1. What is the electron geometry (shape) around Q in each
molecule?
2. What is the polarity of the Q-H bond (polar vs nonpolar)? How did
you determine this?
3. Which molecule, QH3 or Q2H2, is expected to have a higher
boiling point? Support your answer using the concept of
intermolecular forces.
4. The compounds Assanium xoride and elementium dudide react
according to the following equation:
4.Element masses:
Element Molar Mass (g/mol)

31.22
40.32
O is oxygen.
Calculate the mass (in g) of E 2(XO3)3 that could be produced by the
reaction of 2.51 g of A 2XO3 and 6.55 g of EDO2. Show all work.
5. Write an equation (using full nuclide symbols) showing plutonium242 undergoing beta decay.
2. Monica, if you had 5 layers of plastic shielding between you and the
decaying plutonium, would you be concerned about your radiation
exposure? Explain.
