Most widely held works by Wexler Film Productions
Electrochemical cells ( visu )
3 editions published between 1989 and 2008 in English and held by 73 libraries worldwide
Describes the construction and operation of an electrochemical cell. Time-lapse photography of the changes at the electrodes and animation of the cell processes show the nature of the electrode reactions, the motion of the electron and ion currents, and the relationship between concentrations and cell voltage. Extreme close-ups of a hydrogen electrode illustrate its operation and lead to a discussion of the table of E⁰ values
Chemical families ( visu )
4 editions published in 1989 in English and held by 51 libraries worldwide
A display of actual samples of over 70 elements demonstrates methods by which chemical similarities among the elements have provided a basis for dividing them into families. By experiment and observation, elements are classified as metals or nonmetals, and some are shown to be chemically reactive, while others are inert
Equilibrium ( visu )
3 editions published between 1989 and 2008 in English and held by 45 libraries worldwide
Deals with three questions: what is chemical equilibrium, how does the chemist recognize it, and how does one explain it. Stresses the dynamic nature of equilibrium and uses radioactive tracers to demonstrate the dynamic behavior of substances at equilibrium in a closed system. Uses an analogy in terms of fish population in two connected bowls, and animation using molecular models, to present the concepts
The hydrogen atom : as viewed by quantum mechanics ( visu )
2 editions published in 1989 in English and held by 36 libraries worldwide
Uses the hydrogen atom to present the current view of atomic structure given by quantum mechanics
Gases and how they combine ( visu )
4 editions published between 1989 and 2008 in English and held by 34 libraries worldwide
Shows some properties that distinguish gases. The volume of ammonia and hydrogen chloride that combine are measured quantitatively, and simple integer volume ratios are measured for the combinations of hydrogen and chlorine. Interprets these simple integer ratios in terms of Avogadro's hypothesis
The Rates of chemical reactions ( visu )
3 editions published between 1989 and 2008 in English and held by 34 libraries worldwide
Illustrates the mechanisms of some simple chemical reactions. Explains the effect of temperature, activation energy, geometry of collision, and catalysis upon the rate of reaction
Acid base indicators ( visu )
2 editions published in 1989 in English and held by 31 libraries worldwide
Uses the proton donor-acceptor theory to interpret the experimental behavior of acid-base indicators. Experiments and animation show the effects on indicators of changing acidity, determines equilibrium constants of four indicators, and arranges the indicators in order of decreasing acid strength. Shows the competition among bases for protons by mixing the indicators and illustrates that each changes color at different total acidity
Gas pressure and molecular collisions ( visu )
4 editions published in 1989 in English and held by 30 libraries worldwide
The relationship between gaseous pressure and molecular collisions is explored in order to relate the macroscopic properties of gases to the kinetic behaviour of molecules using dynamic models and experiments
Catalysis ( visu )
2 editions published in 1989 in English and held by 30 libraries worldwide
Emphasizes that catalysts are typical chemical reactants, unique only in that they are regenerated during reaction. Animation shows what takes place on the molecular level in a catalyzed reaction. Potential energy curves give the relationship between uncatalyzed and catalyzed reactions
Molecular structure and health : a revision of Biochemistry and molecular structure ( visu )
2 editions published in 1989 in English and held by 20 libraries worldwide
Demonstrates the relationship of molecular structure to biological activity using sulfanilamide as an example. Explains that some compounds structurally similar to those in cell chromosomes may stop cancer. Uses time lapse microphotography to show how 5-fluorouracil acts on cancer cells
Ionization energy ( visu )
2 editions published in 1989 in English and held by 19 libraries worldwide
Presents two methods of measuring ionization energy--photo-ionization and electron bombardment. Shows the use of a high vacuum system with a simple conductivity cell. Demonstrates the photo-ionization of sodium by the use of mercury light source and monochromator with sodium and three inert gases. Uses animation to show what occurs on the atomic level during the ionization process. Explains the relation of ionization energy to chemical reactivity
Nitric acid ( visu )
2 editions published in 1989 in English and held by 19 libraries worldwide
Applies fundamental principles to the descriptive chemistry of nitric acid. Demonstrates how nitric acid acts as an acid, as a base, and as an oxidizing agent. Includes live action, animation, molecular models, activation energy curves, and potential energy diagrams
Mechanism of an organic reaction ( visu )
2 editions published in 1989 in English and held by 18 libraries worldwide
Studies the hydrolysis of an organic ester to show that the discovery of a reaction mechanism includes a determination of the chemical equation, the structures of the reactants and the products, the fate of each atom of the reactants, and the structures of the intermediate molecules. Discusses the concepts of bond polarity and the effect of varying structures of one reactant. Explains that the use of OAH and its detection on the mass spectrometer provide critical experimental data for the particular mechanism of ester hydrolysis
Chemical bonding ( visu )
2 editions published in 1989 in English and held by 18 libraries worldwide
Illustrates electrical interactions among the charged particles in two atoms and shows how these interactions can result in chemical bonding
Vanadium, a transition element ( visu )
3 editions published in 1989 in English and held by 17 libraries worldwide
Studies vanadium as a typical transition element. The different oxidation states of vanadium and the corresponding colors are observed and then identified by means of a quantitative titration of vanadium (II) solution with cerium (IV) solution. The oxidation states and the observed colors are correlated with the electronic structures using an orbital board. The reaction with hydroxide ion and the formation of complex ions containing vanadium in different oxidation states are demonstrated. The variations in chemical properties are discussed in terms of ion size and charge density (charge/size)
Hope is not a method III ( visu )
2 editions published in 1984 in English and held by 17 libraries worldwide
Provides up-to-date information on methods of birth control. Includes animation
Electric interactions in chemistry ( visu )
2 editions published in 1989 in English and held by 17 libraries worldwide
Demonstrates the relation of electric force to distance of separation of charged bodies and shows how this relation helps to explain ion migration and chemical reactions. The migration of positive and negative ions in an electric field and their mutual precipitation are shown in time-lapse photography and in animation
Live or die. ( visu )
3 editions published in 1978 in English and held by 15 libraries worldwide
Through the autopsy findings of two unrelated individuals, a pathologist reconstructs the lifestyles which led to their premature deaths. Points out that each individual is responsible for his or her own health and well-being
The Transuranium elements ( visu )
2 editions published in 1989 in English and held by 15 libraries worldwide
Five eminent scientists--Darleane Hoffman, Glenn Seaborg, Burris Cunningham, Stanley Thompson, Albert Ghiorso--speak of their contributions to gaining chemical knowledge leading to the synthesis of elements heavier than uranium. They describe the research carried on from the 1940's to the 1960's, which lead to the understanding of the transuranium elements as homologs of the lanthanide series in the periodic table. Hoffman concludes with a discussion of recent work and predictions of future discoveries
Vitamins from food ( visu )
6 editions published between 1968 and 1978 in English and held by 13 libraries worldwide
Dramatizes the stories of how Dr. Lind and Dr. Eijkman discovered their respective cures for scurvy and beriberi, explains how the body uses vitamins, detailing co-enzyme metabolism, and suggests the kinds of food sources that will supply all the vitamins we need
