Question: Methylamine, CH3NH2, is a weak base.CH3NH2(aq)+H2O(l)⇄CH3NH3+(aq)+OH-(aq)If the pH of a 0.035 M solution of the amine is 11.56 , what is the value of Kb ?Kb= 2 CH3NH2(aq)+H2O(l)⇄CH3NH3+(aq)+OH-(aq) ...
2. (CH3)2NH 5.1 x 10-4pKb = 3.3 STRONG BASE 3. C6H5CH2NH2 (benzyl amine) pKb = 4.67 STRONG BASE 4. C6H5NH2 (Aniline) pKb = 9.42 WEAK BASE 5. C6H5CH2NHCH3 (N-methyl benzyl amine) Now I know that arylamines are weaker bases than alkylamines, therefore 1,2 are eliminated....

4D,E). The work could suggest that the regulation of Rab5 may not be the major, or generic, function of RABEP2. Even in the original work demonstrating Rab5 interaction the regulation of endosomal function by RABEP2 was relatively weak, and supports the likelihood of Rab5-independent ...
To prepare a buffer of pH 10.5, which buffer system listed below is the best? A、 CH3NH2·HCl —CH3NH2 (pKa =10.65) B、NH3·H2O —NH4Cl (pKa =9.25) C、Na3PO4 —Na2HPO4 (pKa3 = 12.32) D、H2CO3—NaHCO3 (pKa1=6.37)
Strains heterozygous for either one of the two genes encoding the yeast HMGCR (HMG1 and HMG2 27), and therefore carrying three out of four copies of HMGCR show weak but significant resistance to FR171456 (Fig. 2c). Furthermore, the HMG1 HOP strain carrying two from four copies of the...
