Chemical Exercises — Arithmetical Exercises for Chemical Students

Abstract

MR. WOODWARD, who is lecturer on chemistry and physics at the Midland Institute, Birmingham, has printed, under the above title, a set of ten very useful cards, to assist students in familiarising themselves with the more common numerical calculations of chemistry. Each card contains, first the data, and secondly the method of a particular kind of calculation; this is followed by a number of questions. Ten subjects are gone over in this way. I may describe them as: (1) the metric system; (2) conversion of thermometric readings, and reduction of gaseous volumes: (3) specific gravity; (4) formulæ as yielding percentage composition; (5) percentage composition a source of formulæ; (6) weight and chemical effect; (7) volume and chemical effect; (8) reactions of gases; (9) the crith and thermal units; (10) specific atomic, and latent heat. This range is amply sufficient for all ordinary purposes.
