STUDY GUIDE : There will be questions on Equivalent Weight of a Metal

Total Points: Approximately 240 (Final Exam) + 40(Quiz) = 280

1) Eleven short problems on: Density,  Interpolation,  Dilution, Molarity, StoichiometryCalorimetry, 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 vinegar.
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.
