Consider the H-M-H angle around the central atom, M, in the compounds and ions below. Which is the correct order of increasing angle? {eq}NH_{3}, H_{2}S, CH_{3}+ {/eq} 1. {eq}NH_{3} < H_{2}S < CH_{3}+...
It is conceivable that some of the very fine work done in Egypt, long before the invention of " optical " glass, may have been made possible by the use of a liquid lens of this kind. The phenomenon might easily have been accidentally observed; for even a drop of water lying on a ...
Construct an electron-dot diagram for carbonate ion. Draw the structural formulas for the three resonance possibilities for the ion, and estimate the average carbon-oxygen bond order. Draw a partial bond representation of the ion. Draw one of the resonance structu...
The lubricant layer according to the present invention is used in a thin film magnetic recording medium in which a solid surface sliding at a high speed is required to retain its lubricating performance and abrasion resistance for a long period of time, comprising a host-guest complex composed ...
A semiconductor device capable of holding data for a long time is provided. The semiconductor device includes a first transistor, a second transistor, and a circuit. The first trans
5-bis(1-naphthyl-oxadiazole) having a highest occupied molecular orbital (HOMO) which is different from a HOMO of said poly(N-vinylcarbazole), and said hole transport layer emitting light within a visible light wavelength range by excitons formed by recombinations of the electrons and the holes...
dipole, or otherwise affects the local field at the main QM section, it can be worse than a vacuum with a somewhat more distant boundary. However, QM/MM is often considered as a useful compromise between the requirements for computer resources and the requirements for QM accuracy in ...
