Q.6
Liquid bromine (Br2) boils at 58.8oC and has a standard enthalpy of vaporization equal to 29.6 kJ/mol. Calculate the entropy change when 159.8 g of bromine vaporizes. Provide an answer correct to 3 significant figures.
What is the change in the internal energy of a system in which 66.1 kJ of heat is transferred to the surroundings while the surroundings do 44.0 kJ of work on the system? Provide an answer that is correct to 3 significant figures.

Assume that random guesses are made for seven multiple choice questions on an SAT test, so that there are n=7 trials, each with probability of success (correct) given by p=0.55. Find the indicated probability for the number of correct answers.
Find the probability that the number x of correct answers is fewer than 4.
Over the past 40 years, technological advances
have reduced the cost of computer chips. How do
you think this has affected the market for computers?
For computer software? For typewriters?
Consider the markets for film streaming services,
TV screens, and tickets at movie theaters.
a. For each pair, identify whether they are
complements or substitutes:
r Film streaming and TV screens
r Film streaming and movie tickets
r TV screens and movie tickets
b. Suppose a technological advance reduces the cost
of manufacturing TV screens. Draw a diagram to
show what happens in the market for TV screens.
c. Draw two more diagrams to show how the
change in the market for TV screens affects the
markets for film streaming and movie tickets.
