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.

A Methane Balloon Inflation Chamber Curtis J. Czerwinski and Tanya J. Cordes While several lecture demonstrations are possible using methane-filled balloons, it is often inconvenient to prepare these balloons since the pressure from standard laboratory and lecture hall gas nozzles is too low. As a solution to this problem, a methane balloon inflation chamber, prepared from a translucent 3.5-gallon pail and an aspirator or house-vacuum, provides an inexpensive and convenient method for inflating balloons in laboratories or lecture halls. Prepared in this way, methane-filled balloons can be used to demonstrate the effects of vacuum, the lifting power of low-density gases, and the explosive combustion of methane.

Slide Projector Corrosion Cell Silvia Tejada, Estela Guevara, and Esperanza Olivares The process of corrosion can be demonstrated in a slide projector, since the cell is in the shape of a slide, or on the stage of an overhead projector by setting up a simple galvanic cell. Corrosion occurs as the result of a galvanic cell reaction, in which the corroding metal acts as the anode. Several simple demonstrations relating to corrosion are described here.
