The reaction quotient is a way of quantifying the relative amounts of reactants and products for a reversible reaction at any point in time. It is given the symbol **Q**, and you can calculate it using a simple formula involving the concentrations (technically the "activities") of the pr...

The Q-TOF configuration allows collimation of the ion beam, as well as the option of mass selection in Q1 and fragmentation in a radiofrequency-only quadrupole. They can produce high-quality MS/MS spectra, including high-resolution data for the determination of molecular formulae. Both MS and...
As in a complex arithmetic formula, you can use parentheses simply to group terms. 正如在复杂的数学公式中,您可以简单地使用括号来给术语分组。 28. 30kb Republicans don’t have a mandate to cut spending; they have a mandate to repeal the laws of arithmetic. 共和党并没有得到削减开支的授权...
CONSTITUTION:Coenzyme Q is pepared by the catalytic oxidation of reduced coenzyme Q of formula (n is integer 1-12) (2,3-dimethyoxy-5-methyl-6-prenyl hydroquinone) in a hydrophobic solvent (e.g. nexane, petroleum ether, etc.) with manganese dioxide. The concentration of the reduced ...
When the reaction of HQ with Ba was carried out in the presence of mono-, bi- or poly-dentate O- or N-donor ligands, derivatives of formula BaQ2Ln(H2O)m have been obtained, depending on the nature of the ancillary ligand and reaction conditions employed [L = 2,5,8,11,14-pentaoxa...
