The mole is complicated and the textbook heavy, a stubborn concept explained to me by a man wearing a tweed jacket with a pickle pin on the lapel. The pin is from a ketchup factory, not a chemistry lab, and it is intended to be funny—funnier than the half empty beakers in tippy me...
化学博士Dr.Sara的寄语 The mole day celebration is held by DP chemistry students just after they finished the topic 1: stoichiometry relationship in DP chemistry. So this activity also is set as a CAS activity to deliver the important concept “mole” in chemistry. The students well designed th...

The impracticalities were explained to her from all angles, but she was insistent. A compromise was reached. When she was old enough she would spend spring, summer and autumn teaching callisthenics and chemistry at a school for the daughters of impecunious gentlemoles, and in the winter a...
celebrate it, expand students’thinking, develop their interests in Chemistry. Students in six groups designed six experiments, explained and displayed them spontaneously,which not only helps consolidate the basic knowledge of chemistry, but also cultivate ...
However, these investigations are tedious and are of little use for a widespread study of silaethene chemistry. Therefore the generation of silaethenes in solution (from vinylchlorosilanes and tert-butyllithium) is the preferred method. Numerous differently substituted silaethenes have been generated...
disubstitued cyclohexene compounds, (Iae – Iee) values are +2.1 (X = COOC2H5) and +6 kcal mol1 (X = C≡N).For trisubstitued compounds, the results can be explained by an increase of diequatorial interactions in all equatorial stereoisomers.The synthesis and the isomer identifications ...
brands need more information about the chemical formulations used on their products. In the apparel industry, this has been achieved by “Screened Chemistry”, a program first developed by LS&Co. in 2013. A later blog post will describe what Screened Chemistry is and how it is implemented into...
