Three modes of approach of CHCl to the oxygen of the nucleophile were examined: and to the lone pair on the nitrogen in the molecular plane, and an approach along the π system of the oximate anion. The AM1 method differed markedly from the two methods, both in the reactivity order of...
What is an example of reactivity? Reactivity is the ability of matter to combine chemically with other substances. For example, iron is highly reactive with oxygen. When it combines with oxygen, it forms the reddish powder called rust (see Figure below). Rust is not iron but an entirely dif...

The dynamic test (Fig. 7(B)) demonstrated the wall reactivity under the brutal humidity variation. The wall adsorbed an important quantity of water quickly, which led to a reduction in the relative humidity of the room to 60%RH. Moreover, it appeared that the first few centimeters of the...
the experiments were buffered at approximately the Ni-NiO oxygen buffer due to the presence of Ni metal filler rods, which occupied the bore of the autoclave not occupied by the Au capsules. Temperatures were measured externally by a thermocouple tip inserted into the end of autoclave near the...
the reactivity towards SO2uptake was highest on δ-MnO2but lowest on β-MnO2, with a geometric uptake coefficient (γobs) of (2.42 ± 0.13) ×10–2and a corrected uptake coefficient (γc) of (1.48 ± 0.21) ×10−6for the former while γobsof (3.35 ± 0.43) ×10...
Compared to sterilization, changing oxygen concentrations or acidification had little or no effect on P release. In these sediments, phosphorus and iron movements were independent. Most of the total dissolved iron seemed to be linked to humic acids, but not phosphorus....
Element A has an atomic number of 11. Compare its atomic radius and ionic radius. Identify and compare trends on the periodic table, including reactivity and relative sizes of atoms and ions. Use the trends to explain the proper...
The mutation L14A has been shown to have a large effect on the reactivity of Pc toward PSI (63). On the other hand, this mutation has only minor effects (a 2-fold decrease in reaction rates) on the reduction of Pc by Cf.2 This is in agreement with the location of Leu-14 at ...
The reactor consisted of a 10-650-cm steel cylinder (diameter 6 length) closed on one end with a circular steel plate. The closed end was perforated with a 1/40-brass male compression fitting to serve as an inlet for N2, which was used to purge the reactor of ox...
