Modifying and Validating the Colorado Learning Attitudes about Science Survey for Use in Chemistry  Jack Barbera, Wendy K. Adams, Carl E. Wieman, and Katherine K. Perkins
The chemistry version of the Colorado Learning Attitudes about Science Survey (CLASS-Chem) is a new instrument designed to measure the effects of students' beliefs on learning and to understand how educational practices influence these beliefs in order to guide chemistry instruction.

Manual Data Processing in Analytical Chemistry: Linear Calibration  Dora Melucci
Most science students are familiar with Excel spreadsheets, but determining which of Excels statistical functions perform a calculation equivalent to a classical equation and calculating errors with Excel are not trivial exercises.

The Empirical Formula of Silver Sulfide  Carlos Alexander Trujillo
An experiment is described that allows students to experimentally determine an empirical formula for silver sulfide. At elevated temperatures, silver sulfide reacts in air to form silver, silver sulfate, and sulfur dioxide. At higher temperatures (~960C) silver sulfate decomposes to produce metallic silver.

The Decomposition of Zinc Carbonate: Using Stoichiometry To Choose between Chemical Formulas  Stephen DeMeo
To determine which formula corresponds to a bottle labeled "zinc carbonate", students perform qualitative tests on three of zinc carbonate's decomposition products: zinc oxide, carbon dioxide, and water. Next students make quantitative measurements to find molar ratios and compare them with the coefficients of the balanced chemical equations. This allows the correct formula of zinc carbonate to be deduced.

Formation and Dimerization of NO2 A General Chemistry Experiment  April D. Hennis, C. Scott Highberger, and Serge Schreiner*
A general chemistry experiment which illustrates Gay-Lussac's law of combining volumes. Students are able to determine the partial pressures and equilibrium constant for the formation and dimerization of NO2. The experiment readily provides students with data that can be manipulated with a common spreadsheet.
