Classify the acid and base as either a strong acid (SA), weak acid (WA), a strong base (SB), or weak base (WB): CH_2CO_2H. Classify the acid and base as either a strong acid (SA), weak acid (WA), a strong base (SB), or we...
NH3 is a weak base (Kb = 1.8 x 10-5) and so the salt NH4Cl acts as a weak acid. What is the pH of a solution that is 0.092 M in NH4Cl at 25 degrees Celsius? NH_3 is a weak base (K_b = 1.8 x ...

A freshly prepared aqueous solution of Pd(NH3)2Cl2 does not conduct electricity. Is this compound to be regarded as a strong or weak electrolyte? Explain in terms of its structure.
The calculated results display that NH3 molecules can be adsorbed on the pristine SiCNT via a weak physical interaction, which is much weaker than those of NH3 adsorption on Sc and Ti-doped SiCNTs. All of Sc and Ti-doped SiCNTs can absorb single and multiple NH3 molecules with the ...
Sugar beet heterochromatin can be distinguished in large intercalary blocks on both chromosome arms, in pericentromeric and centromeric heterochromatin as well as in smaller subtelomeric and interspersed heterochro- matic sites, which are visible as strong DAPI staining in metaphase spreads (e.g. Fig....
strong oxidation by NO2forces Cu ions to exist mainly as CuIIspecies (fw-Cu2+and NH3-solvated CuIIwith high CNs), which impedes the mobility of Cu species. The SCR reaction occurring at these CuIIsites with weak mobility shows a higher energy barrier than that of the standard SCR reactio...
Zinc metal complexes have a strong absorption peak between 350 nm ∼ 400 nm, and under the excitation peak of 365 nm wavelength, the complex has a weak emission peak at 540 nm. According to Fig. 2(a) Two emission peaks can be observed at the excitation wavelength at 365 nm. The emis...
Ammonia, NH3, is a weak base with a Kb value of 1.8 * 10-5. What is the pH of a 0.460 M ammonia solution? pH of NH3 Weak base ionizes and has ionization constant Kb at equilibrium. In order to solve for the value for ionization constant K...
All above and population analysis demonstrate that the ONIOM may be a reliable scheme in the study of weak interactions while it is a controversial approach and should be applied cautiously in the case of strong interactions. We also probed the effect of tube length and diameter on the ...
