Text Exercises, Part III
Prepare written answers to the following assignments from Introductory Chemistry:
Exercise 104 in Ch. 17
Exercise 118 in Ch. 18
Exercise 98 in Ch. 19
Chapter 17: Ex. 104
A radiometric dating technique uses the decay of U-238 to Pb-206 (the half-life for this process
is 4.5 billion years) to determine the age of the oldest rocks on Earth and by implication the age
of Earth itself. The oldest uranium-containing rocks on Earth contain approximately equal
numbers of uranium atoms and lead atoms. Assuming the rocks were pure uranium when they
were formed, how old are the rocks?
Chapter 18: Ex. 118
In Chapter 13, we learned about the “dirty dozen”—twelve chemical compounds that have been
targeted by governments around the world to be banned. These compounds are known as
persistent organic pollutants (POPs) because once they enter the environment, they remain for
long periods of time. Examine the structures of the following compounds. What functional
groups can you identify within the compounds? (They may have more than one.) What structural
features do many of these compounds have in common?
