1.
a) Draw lithium bromide (LiBr) and hydrogen bromide (HBr) in the solid state. Include at least four formula units in each drawing. Use appropriately sized circles to represent ions and Lewis Structures to represent molecules. Make sure to indicate what the components of your drawings represent.
b) In the drawings, draw and label the strongest interactions that exist between particles (ie ions or molecules).
c) Claim: The melting point of LiBr is _____ (higher than/ lower than/ the same as) the melting point of HBr.
d) Evidence: List all of the interactions that are overcome when each substance melts.
LiBr:
HBr:
e) Reasoning: Use the interactions you listed (in part b) to explain why you made your claim (in part c). Make sure to include forces and energy.
Homework Answers
Part c). The melting point of LiBr is higher than the melting point of HBr.
Part b), part d) and part e). LiBr: High lattice energy, because it is an ionic solid.
HBr: Dipole-dipole forces, dispersion forces, polar-covalent liquid in water
Hence the melting point of LiBr is higher than that of HBr.

Grignard reagent THE GRIGNARD REAGENT-PREPARATION AND REACTION In this experiment, you will prepare a Grignard reagent, phenyl magnesium bromide, from bromobenzene and magnesium metal. The Grignard reagent will then react with methyl benzoate to form triphenylmethanol. Introduction Grignard reagents, such as organomagnesium halides, were discovered in 1910 by French chemist Victor Grignard. The Grignard reaction is one of the most general methods for carbon- carbon bond formation in all of organic chemistry....

Q: Compare the assumptions of physician-centered and
collaborative communication. How is the caregiver’s role different
in each model? How is the patient’s role different?
Answer: Physical-centered communication involves the specialists
taking control of the conversation. They decide on the topics of
discussion and when to end the process. The patient responds to the
issues raised by the caregiver and acts accordingly. On the other
hand, Collaborative communication involves a...
