Communicating about Matter with Symbols: Evolving from Alchemy to Chemistry  Luigi Fabbrizzi
Alchemists used a secret language and arcane symbols to indicate substances and procedures. When alchemy became quantitative and evolved into the discipline of chemistry, those symbols were supplanted by abbreviations and formulas. However, chemical communication can remain mysterious to the uninitiated.

A Short History of Three Chemical Shifts  Shin-ichi Nagaoka
Regrettably, the term "chemical shift" to designate the position of a spectral signal has a poor reputation as a technical term. Nevertheless, the "chemical" environment around an atom of interest influences the electronic environment and hence, leads to spectral shifts, making the prefix "chemical" appropriate.

Single-Molecule Electronic Measurements with Metal Electrodes  Stuart Lindsay
The process of transferring electrons from one metal electrode to another via an intervening molecule differs from electrochemically or optically-induced electron transfer in important ways. The simplest process of ballistic electron transport with no charge localization on the molecule (tunneling) should be easy to understand quantitatively, yet experimental reports and theoretical calculations can differ by orders of magnitude. Here, we show how many of the discrepancies are resolved with measurements carefully constructed to provide data on single molecules connected to electrodes in well-defined ways.

Finding Chemical Anchors in the Kitchen  Liliana Haim
We present a series of cooking activities to be carried out as a starting point of a chemistry course in the elementary school. This "kitchen course" is intended for students ages 911 who are new to chemistry. The main purpose is to allow students to practice transferrable skills by handling concrete kitchen materials; they learn classification, ordering, unit conversion, and conservation. The kitchen activities also introduce anchors for chemistry-specific skills such as periodic table conformation and manipulation, chemical equation and chemical formula use, relative mass, and element and compound differentiation.

Defining NA in conjunction with the existing undebatable definition of a mass scale based on 12C mandates, ipso facto, the kilogram metric.

Copper Metal from Malachite circa 4000 B.C.E.  Gordon T. Yee, Jeannine E. Eddleton, and Cris E. Johnson
The experiment starts with a naturally occurring ore, malachite, essentially pure Cu2CO3(OH)2, which is readily available at modest cost in bead form from jewelry stores. Using only a Bunsen burner, a porcelain crucible, and a charcoal briquette, the experiment demonstrates two steps in the ancient processing of copper ore: roasting and reduction. The product is a shiny copper metal bead that can then be hammered, polished, and shown to be electrically conductive.

A New Look at Reaction Rates  Tomislav Cvitas
The rate of reaction, as an intensive quantity characteristic of the process, is obtained by dividing the amount of chemical transformations per time by the volume of the reaction system. The practical definition of the reaction rate found in the literature can then be derived by defining the stoichiometric numbers as changes in the number of specific molecules taking part in the reaction per chemical transformation.

The need for general terms to include all compounds with "water of crystallization" and all compounds with "ammonia of crystallization" has led to the widespread use of "ammoniates" and "hydrates" for this purpose. However, the extension of this practice has certain pitfalls since the ending -ate is now the accepted ending for anions generally.
