Prior to enrollment in CH 115, the student must be able to:

1.     Solve algebraic equations. 

2.     Solve problems involving area, volume, speed, average, or percentage. 

3.     List the basic Metric units for mass, volume, and length. 

4.     List the common prefixes used in the metric system with the appropriate numerical meaning. 

5.     List the basic English units for weight, volume, and length. 

6.     Convert between English measurements and Metric measurements using dimensional analysis. 

7.     List the SI units of measurement. 

8.     Determine the number of significant figures in a measurement or in a calculated value. 

9.     Write a numerical value in scientific notation. Use the appropriate rules for scientific notation to
        perform calculations. 

10.  Use the appropriate rules for rounding-off numbers in all calculations. 

11.  Know the formula for the determination of the density of an object from mass and volume data. 

12.  Use the temperature conversion formulas to convert Fahrenheit temperature to Celsius, and Celsius
        temperature to Fahrenheit. 

13.  Use the method of dimensional analysis along with appropriate conversion factors to express a
        measurement given in one specific unit to another unit. 

14.  Work basic stoichiometry problems that deal with chemical formulas and balanced chemical        equations.

When enrolling in and taking CH 115:

• Enter the CRN for CH 115 and the CRN for CH 115R in the same registration screen (in different boxes).
• Take CH 116 during the same semester as CH 115 if possible. 
• Purchase the textbook early and study early if at all possible.
• Meet with the instructor regularly if you have any problems comprehending!!
• Attend SI, which you will hear about on the first day. Don't wait until exam week, or after you have an exam score you're not happy with! This is a special, FREE help session held weekly, taught by students who succeeded in the course in the past and who sit in lecture with your class. The website for SI is http://main.uab.edu/Sites/undergraduate-programs/general-studies/academic-success/si/. The schedule will be posted a week or two prior to the start of each term. Some students say it helps raise the grade by a letter grade! 
• Attend all recitation meetings and complete the practice problems given. Attendance is mandatory!  Be careful which day/time you select, because you cannot get credit if the recitation section you sign up for doesn't fit your schedule and you are unable to attend. Working these problems can help you prepare for the exams, and (as noted) your work counts in your lecture class grade. Not participating, or not attending the correct section, may make a letter grade difference in your lecture grade!
• If you need to hire a tutor, check our main office (CHEM 201) or our advising website: http://main.uab.edu/chemistry/show.asp?durki=75818.

Save your notes & materials! The final exam in general chemistry II at UAB is comprehensive, covering BOTH SEMESTERS of general chemistry.
