Umland, Jean B. – Journal of Chemical Education, 1984
Discusses an instructional strategy in which stoichiometric reactions are presented in terms of a recipe. Solutions for two different stoichiometric problems are included. (JN)

Gizara, Jeanne M. – Science Teacher, 1981
Discusses a method to solve problems in stoichiometry which can also be applied to other problems involving relationships between constituents in a chemical reaction. Students with little prior knowledge of chemistry can successfully use the method. (Author/SK)

Purser, Gordon H. – Journal of Chemical Education, 1988
Presents calculations that suggest stoichiometric, ionic, and noble gas-metal compounds may be stable. Bases calculations on estimated values of electron affinity, anionic radius for the noble gases and for the Born exponents of resulting crystals. Suggests the desirability of experiments designed to prepare compounds containing anionic,…

Alick, Bonita; Atwater, Mary M. – School Science and Mathematics, 1988
Discusses problem-solving strategies and the successful strategy used to solve stoichiometric problems in general college chemistry courses. Reports that rereading problems, recalling a related concept, and reasoning deductively/inductively are the most heavily used strategies among 13 categories. (YP)

Sumrall, William J. – Science Teacher, 1991
Presents four stoichiometric problems and their solutions that use spot metal prices quoted from the newspaper to integrate economics and chemistry. (MDH)

Figueira, Alvaro Rocha; And Others – Journal of Chemical Education, 1988
Examines the thermal decomposition of sodium bicarbonate to sodium carbonate. Encourages students to predict the end products and to use the stoichiometric results to determine if their predictions are correct. (MVL)

Gold, Marvin – Journal of Chemical Education, 1988
Describes a simple laboratory procedure for changing sodium carbonate into sodium chloride by adding concentrated HCl to cause the reaction and then evaporating the water. Claims a good stoichiometric yield can be obtained in one three-hour lab period. Suggests using fume hood for the reaction. (ML)

Bogner, Donna, Ed. – Journal of Chemical Education, 1986
Presents two different approaches to teaching stoichiometry. One uses a question and answer technique and the familiar concepts of "pounds" and "degrees" to describe the concept. The second example introduces stoichiometric relationships used in the well-known camper's snack known as S'mores. (TW)
