The Correlation of Binary Acid Strengths with Molecular Properties in First-Year Chemistry  Travis D. Fridgen
This article replaces contradictory explanations for the strengths of different binary acids in first-year chemistry textbooks with a single explanation that uses a BornHaber cycle involving homolyic bond dissociation energies, electron affinities, and ion solvation enthalpies to rationalize trends in the strengths of all binary acids.

Introduction of Differential Scanning Calorimetry in a General Chemistry Laboratory Course: Determination of Thermal Properties of Organic Hydrocarbons  Ronald DAmelia, Thomas Franks, and William F. Nirode
Differential scanning calorimetry (DSC) is a rugged, easy-to-use instrumental method for thermal analysis determinations. The work described herein discusses the use of DSC in a general chemistry laboratory course to determine thermal properties such as melting points, ?fusionH, ?fusionS, and introduce the concept of polymorphism for organic hydrocarbons.

Revisiting Molar Mass, Atomic Mass, and Mass Number: Organizing, Integrating, and Sequencing Fundamental Chemical Concepts  Stephen DeMeo
It is often confusing for introductory chemistry students to differentiate between molar mass, atomic mass, and mass number as well as to conceptually understand these ideas beyond a surface level. One way to improve understanding is to integrate the concepts, articulate their relationships, and present them in a meaningful sequence.

Sherlock Holmes and the Case of the Raven and the Ambassador's Wife: An Inquiry-Based Murder Mystery  Nathaniel Grove and Stacey Lowery Bretz
In the accompanying investigation, students help Sherlock Holmes solve the poisoning death of Holly Bernard-Schneider, the wife of the German ambassador to England. Hints are placed throughout the story to help students in their choice of experiments. These experiments include flame tests, qualitative analysis, molar mass determination using freezing point depression, and identification of crystal shapes. Though intended for use as a culminating activity, the unit can be easily modified to be used as separate modules throughout the course of the year.

Synthesis and Physical Properties of Liquid Crystals: An Interdisciplinary Experiment  Gerald R. Van Hecke, Kerry K. Karukstis, Hanhan Li, Hansford C. Hendargo, Andrew J. Cosand, and Marja M. Fox
This experiment features an investigative approach designed for the introductory science or engineering major and integrates concepts in the fields of chemistry, biology, and physics. Derived from faculty research interests, this novel experiment gives students the opportunity to draw conclusions from tests performed to illustrate the connection between molecular structure and macroscopic properties. The chemical synthesis of the compounds studied further enhances the connection between molecular structure and macroscopic physical properties. The results of two separate physical measurements, refractometry and absorption spectroscopy, are combined to calculate a microscopic, but very practical, property of chiral nematic liquidsthe pitch of the helix formed in the liquid crystalline phase.

Some Insights Regarding a Popular Introductory Gas Law Experiment  Ed DePierro and Fred Garafalo
This paper alerts readers to a potential source of error in one approach to the Dumas method as it is often practiced in introductory chemistry laboratories. The room-temperature vapor pressures of volatile compounds that might be considered as unknowns for the experiment lead to determined molar masses that are too low. The greater the vapor pressure of the compound, the lower the determined molar mass will be, when compared to the accepted value.
