We use Optical Character Recognition (OCR) during our scanning and processing workflow to make the content of each page searchable. You can view the automatically generated text below as well as copy and paste individual pieces of text to quote in your own work.
Text recognition is never 100% accurate. Many parts of the scanned page may not be reflected in the OCR text output, including: images, page layout, certain fonts or handwriting.
1932 in Science, describes experiments in surface chemistry which shed light on properties of molecule. Velocity of Chemical Reactions. (10 min) 1937. 16sd-$50. EBFilms (write for nearest distributor). Describes with photography and animation, the effect of the nature, the concentration, and ihe temperature of reacting substances on the rate of chemical reactions. Practical examples with wood, aluminum, iron, and other substances are given to illustrate these phenomena. The dynamics of reversible reactions and of chemical •equilibrium are shown by schematic drawings that give clear conceptions of rather abstruse processes. SLIDE FILMS Atmosphere, Tl>e. $2.
