If the lab work is faulty, the conclusions will be faulty. It is worth noting that, in grading the experiment, the instructor normally examines the students' results along with the conclusions. If the student's answer is not supported by the student's own figures, the grade suffers. This is the norm for CHE 105 laboratory experiments. The latter are obtained by the student.
Students quickly learn how to frame a question properly.
You must bring textbook and calculator to each lecture and recitation. You must bring lab manual, calculator and eye protection to each lab session. Students are expected to attend those courses for which they are registered. There is a correlation between attention to attendance and good grades. You are responsible for any and all material covered, assignments made or to be turned in, announcements, etc.
