The following problem
set havc been taken from T.L. Brown
H. E. Lemay, B. E. Bursten, & J. R. Burdge, *Chemistry: The Central Science*,
Ninth Edition. The problem sets, complete with worked solutions, should provide
the student with a preliminary measure of his or her skills. Try to understand
the basic concepts __before__ attempting the problems. Without an understanding
of basic concepts, the temptation is to memorize procedures from the worked
solutions and then apply these procedures to other problems. This approach may
work with simple problems but it will not help you to solve all the different
problem types and variations that you are likely to encounter.

Before looking at the solution to a problem try to set up how you would solve the problem. When you
are completely stuck, look at part of the solution for a hint. At some point,
it is imperative that you can solve each of these problems completely on your
own.
