It is chemically active, reacting with certain metals and metal oxides to form bases, and with certain oxides of nonmetals to form acids. It reacts with certain organic compounds to form a variety of products, e.g., alcohols from alkenes. Because water is a polar compound, it is a good...
The infrared spectrum of H2O in dilute solution in each of two non- polar solvents, carbon tetrachloride and carbon disulfide, was obtained employing a Perkin-Elmer double beam spectrophotometer Model 221 with NaCl prism-grating interchange. The five-centimeter-pathlength liquid absorption cell ...
The proposed approach is validated using available experimental data on the dissociation constants of H2O and NaCl and the solubility of both covalent and ion crystals (SiO2, AgCl, Ag2SO4, Ca(OH)2, CaCO3) in H2O-non-polar component (dioxane, Ar, CO2) mixtures. Predicted and experimental data...
The transport properties of the H2O@C60-based nanostructure sandwiched between electrodes are studied using first-principles calculations combined with the non-equilibrium Green’s function formalism. Our results show that the conductance of the H2O@C60 is sensitive to the position of the H2O and its...
this suggests that it should be a well known and a more or less inert molecule. This chap- ter and the following ones clearly show that this is far from true (1). It is a polar molecule, with a marked electric dipole moment of D (1 D ϭ 1 Debye Ϸ ϫ 10Ϫ30 C m ...
It should be noted that several mechanisms, such as polar or non-polar, might be possible for the transformation of azide to tetrazole 61-63. Nitrile formation does not occur in the present work because of the azide ion's nucleophilic attack on the electron- deficient carbon atom64. Rather,...
Invitop is longing to develop more fine products to share with our users in the future. FAQ Q1: Are you factory or retailor? A: We are factory directly, so email to us if you need more. Q2: I am a reseller, I would like to buy many ...

Solvent–solvent or solvent–solute interactions in the presence of water, an excellent polar solvent, are primarily Coulombic in nature; hence a prototype to delve into these interactions may be simulated by externally applying an external electric field to water clusters. Strong molecular electric fi...
