Determination of the Formula of a Hydrate: A Greener Alternative  Marc A. Klingshirn, Allison F. Wyatt, Robert M. Hanson, and Gary O. Spessard
This article describes how the principles of green chemistry were applied to a first-semester, general chemistry courses, specifically in relation to the determination of the formula of a copper hydrate salt that changes color when dehydrated and is easily rehydrated with steam.

A Simple Penny Analysis  Nicholas C. Thomas and Stephen Faulk
Describes a simple procedure for determining the zinc composition of U.S. pennies in which the penny zinc core is dissolved in acid and the evolved hydrogen gas is collected by water displacement.

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.
