High School Chemistry Content Background of Introductory College Chemistry Students and Its Association with College Chemistry Grades  Robert H. Tai, R. Bruce Ward, and Philip M. Sadler
Do students who focus on some content areas in high school chemistry have an advantage over others in college chemistry? This manuscript seeks to answer this question through the use of a survey of 3521 introductory college chemistry students. The results indicate that studying stoichiometry in high school was most strongly predictive of college chemistry success.

Assessing the Effect of Web-Based Learning Tools on Student Understanding of Stoichiometry Using Knowledge Space Theory  Ramesh D. Arasasingham, Mare Taagepera, Frank Potter, Ingrid Martorell, and Stacy Lonjers
This paper reports a comparative study using knowledge space theory (KST) to assess the impact of a Web-based instructional software program on students' understanding of the concept of stoichiometry. The software program called Mastering Chemistry Web (MCWeb) allows students to practice problems that emphasize the development of molecular-level conceptualization and visualization, analytical reasoning, and proportional reasoning, as well as learning to recognize and relate different representations in chemistry. The experimental design compared students in two sections taught by the same instructor. One section used the MCWeb instructional software as homework (MCWeb group) while the other section used text-based homework (non-MCWeb group, control).

Mass Relationships in a Chemical Reaction: Incorporating Additional Graphing Exercises into the Introductory Chemistry Laboratory  Stephen DeMeo
The purpose of this article is to increase student involvement with graph construction specifically in the context of introductory laboratory activities that involve mass relationships between reacting substances and products. In this regard, five massmass plots derived from a synthesis of a binary compound from its elements are presented as well as a set of questions to focus learners on the significance of each plot. The benefit of providing learners with these types of graphing activities include the use of higher-order cognitive processes as well as the elucidation of fundamental chemical knowledge such as the law of the conservation of mass, the law of constant composition, limiting and excess reactants, and empirical formula.

Procedure for Decomposing a Redox Reaction into Half-Reactions  Ilie Fishtik and Ladislav H. Berka
The principle of stoichiometric uniqueness provides a simple algorithm to check whether a simple redox reaction may be uniquely decomposed into half-reactions in a single way. For complex redox reactions the approach permits a complete enumeration of a finite and unique number of ways a redox reaction may be decomposed into half-reactions. Several examples are given.

Evaluating Students' Conceptual Understanding of Balanced Equations and Stoichiometric Ratios Using a Particulate Drawing  Michael J. Sanger
A total of 156 students were asked to provide free-response balanced chemical equations for a classic multiple-choice particulate-drawing question first used by Nurrenbern and Pickering. The balanced equations and the number of students providing each equation are reported in this study. The most common student errors included a confusion between the concepts of subscripts and coefficients and including unreacted chemical species in the equation.

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.

This paper describes a simple synthesis of an aqueous-based ferrofluid that may be used in an introductory science or engineering laboratory. This paper also describes a method for repelling both oil- and water-based ferrofluid from solid surfaces that would otherwise be stained by the fluid. Finally, a demonstration of the interaction between ferrofluid and magnetic fields, in which ferrofluid is induced to leap upward by a stack of magnets, is described.

A Closer Look at the Addition of Equations and Reactions  Damon Diemente
Chemists occasionally find it convenient or even necessary to express an overall reaction as the sum of two or more component reactions. A close examination, however, reveals that the resemblance between chemical algebraic equations is entirely superficial, and that the real meaning of addition in chemical equations is subtle and varies from case to case. In high-school courses, students are likely to encounter the addition of equations in thermochemistry, in electrochemistry, and in kinetics.
