aqueous15% sodium hydroxide (47 mL, over 20 min), and water (141 mL, over 30 min). The solutionis stirred for 30 min and the white precipitate is filtered. The filter cake is washed with ethylether (3 × 150 mL) and the organic filtrates are combined, dried with anhydrous sodiumsulf...
calculate the molarity of each ion in a 0.025 aqueous solution of (a) kcl; (b) CuSO4; (c) CaCl2 What is the % concentration (m/v) of a solution prepared by dissolving 160.0 g of CuSO_4 in enough water to make 250 mL of a solution? How many grams of CuSO...
SMase activity was assayed using 250 nM [3H]sphingomyelin in Triton X-100 micelles in the presence of either 5 mM EDTA (hatched bars) or 0.1 mM ZnCl2 (solid bars) for 1 h at 37°C at pH 5.0. ASM, acid SMase; NP-A, Niemann-Pick type A. Naturally occurring point mutations in ...
Kinetic analysis of nSMase3 in the presence of PS revealed for SM a Km of 18.71 μm and a Vmax of 1.67 pmol/μg/h (Fig. 4B). MgCl2 and MnCl2 at 5 mm stimulated nSMase3, whereas CaCl2, CuCl2, or ZnCl2 did not change nSMase3 activity (Fig. 5A). PS stimulated nSMase3, ...
Fly ash (FA) is a by-product of power, and incineration plants operated either on coal and biomass, or on municipal solid waste. FA can be divided into coal fly ash, obtained from power plant burning coal, flue gas desulphurisation FA, that is, the by-product generated by the air po...
硼氢化钠通常不能用来直接还原羧酸,但是Lewis 酸的存在可大大提高其还原能力,从而用于羧酸的还原。由于LAH 和硼烷的价格相对要贵,因此工业上大量生产时,一般都应用该方法,比较常用的体系为:NaBH4-BF3, NaBH4-ZnCl2. J. Org. Chem., Vol. 63, No. 12, 1998. ...
Determine whether or not the following reaction is a precipitation reaction. 3H2(g)+N2(g)→2NH3(g) Precipitation reaction: Two different aqueous salt solutions are mixed to obtain a precipitate. The precipitate is a solid substance that does not dissolve in water (...
ZnCl2 Molar Mass: The molar mass corresponds to the mass per mole of a reagent or a compound. With this quantity, we can determine the number of moles of a substance given its mass, by simply dividing the measured mass by the molar ...
How much energy is liberated when 2.0 moles of electrons flow from the anode to the cathode in a voltaic cell with an electrical potential of 3.0 V? With respect to beta-oxidation, why is regulation is important? Write the net ionic equation for the reaction of ...
