Answers
This is, in large part, a sample final exam from a colleague of mine.
Our formula sheet will be identical to the one below.
The Chemistry Data sheet will be identical to the one we had for the MidTerm Exam; but
some extra formulas will be provided for crystallography.
This sample is for orientation only; the actual exam might be substantially different; it probably
will have more concept questions, rather than calculation problems.
This is a closed book exam. You may use a non-programmed calculator, the attached chemistry data sheet and
the formulas given below.
