Writing has a role of increasing importance in the teaching of chemistry. Analysis of the use of this writing can be aided by classifying writing by types such as expressive, poetic, transactional, empiricist and contingent. The status of chemistry t

The learning of chemistry is described as a process analogous to the process of making chemical discoveries. Historical examples are given to show how chemists have used their insight to break out of a conceptual loop in order to advance the science.

The writing across the curriculum movement began in American col leges and universities in the mid 1970s as an effort by the faculty to spread the responsibility for improving student writing abilities beyond freshman Eng lish. Now there are over fou

The deuterium-labeled 6,9-[(CH3)2S]2-2,4-D2B10H10 is formed regiospecifically from 2,4-D2B10H12 and (CH3)2S. Likewise, the deuterium labels are retained in the same relative locations when 6,9-[(CH...

Electrophilic deuteration of decaborane(14) is studied using aluminum chloride as the catalyst with the exchanging atom, hydrogen or deuterium, provided by an aromatic compound. The reaction appears to occur on the solid surface of the catalyst. Stud

Among the properties of solutions such as boiling point elevation is a little-known colligative property described in 1890 by Walther Nernst and called "reduction of solubility". In common with the other colligative properties, it can be used for det
