Chem 113... General Chemistry Laboratory
FINAL EXAM .... SPRING 2017
Thursday – May 4, 2017; 11:45 AM – 2:45 PM
Rooms: Boyden 100, Smith 220 See...... Assigned Room and Seat
Please check Your Grades to make sure they are complete and correct.
Absolutely NO CELL PHONES!
Not even for checking time or for use as a calculator!
You will need a Calculator with logs (!) and a pen or pencil.
You may bring in and use one… HANDWRITTEN (not Xeroxed) 4" X 6" card (both sides) of notes.
Seats will be assigned. Please take ASSIGNED SEAT in assigned room
MATERIAL to be COVERED by SPRING 2017 FINAL not available as yet.
See PreLabs for Typical Questions
Most calculations will be similar to those in the EXPERIMENTS
4.184 j/oC g
0.0821 L atm/mol K
Fall 2016 (last Fall’s) STUDY GUIDE
Total Points: Approximately 240 (Final Exam) + 40(Quiz) = 280
short problems on:
Density, Interpolation, Dilution, Molarity,
Beer's Law, pH calculations. Remember to use Kelvin temperature when
solving gas law problems.
NOTE: The GRADE on this page will count both as your QUIZ GRADE as well as being part of the FINAL EXAM. These 40 points really count as 80 points in your overall total points
2) True-False questions: 3 or 4 questions each on Density, Calorimetry, pH, Hydrate, Molar Volume, Periodic Table. WARNING: False statements circled as True will lose points. T-F statements taken from those used in computer programs.
3) Calculate: the density of a liquid and/or the density of an irregular solid using a pycnometer. Understand what you did in the lab because the problem ,while basically identical with what you did in the lab, may be presented in a slightly different way. Solvay problem. Chromatography- what is it? Read a chromatogram. Calculate: Rf
4) Be able to write
directions for identifying an UNKNOWN given reactions of the possible UNKNOWNS.
Be specific and brief (100 words max--"Look at the table and figure it
out" is not an acceptable answer!) Name and give uses for common chemicals.
Properties of gasses studied in NonMetals and Pollution; the environmental aspects of these gasses; their formulae. Understand Acid Rain, Global Warming, the Greenhouse Effect. Which are acids or bases.
5) Calculate: the % water in a hydrate and/or the formula of a hydrate. Solve a Spectroscopic Analysis of copper problem.
6) Acid base titration; Analysis of
Understand the basic calculations in the Equivalent Weight of a metal, both the moles of gas released and the acid used up..
7) CALORIMETRY; Specific Heat and Atomic Weight (Rule of DuLong and Petit) of a metal calculations. Errors in Specific Heat measurements. Calculation of Heat of Reaction.
8) Molar Volume of Oxygen from volume and mass
of gas collected from decomposition of KClO3.
Calculate the % KClO3 in a sample from mass of Oxygen collected.
Given experimental errors, determine the effect on calculated % KClO3 or Molar Volume.
9) Calculate a Molecular Weight using the Dumas
method. Short answers of things you can
meet any day and what you learned about them.
