For the reaction CaCO3(s) = Ca2+ (aq) + CO32- (aq), KspΘ(CaCO3)=2.8×10-9, what is the solubility of CaCO3? A. 5.29×10-4 mol/L B. 5.29×10-5 mol/L C. 1.67×10-4 mol/L D. 1.67×10-5mol/L 如何将EXCEL生成题库手机刷题 > 下载刷刷题APP,拍照搜索答疑 > 手...
For reaction (2), CF3O radicals are prepared by another source: the thermolysis of the dimer CF3OOCF3 and the derived rate constant is k2 = (4.7 ± 0.9) × 1011 cm3 molecule1 s1. Our results are in reasonable agreement with recent measurements using different techniques. 展开 DOI: ...
Atom-to-atom mapping (AAM) is a task of identifying the position of each atom in the molecules before and after a chemical reaction, which is important for understanding the reaction mechanism. As more machine learning (ML) models were developed for retr
The reaction was quenched by adding 20 mM iodoacetamide. Fab was purified by performing ion-exchange chromatography using a HiTrap DEAE FF column (GE Healthcare). Purified SARS-CoV-2 S was incubated in a 1:4 molar ratio with 2H2 or 3C1 Fab on ice for 2 h before being subjected ...
When the reaction was stopped with 2 mol/L H2SO4, the values at 450 nm were detected by an ELISA reader (Thermo Scientific, Vantaa, Finland) and endpoint titers were defined as the highest dilution of sample for which the optical density (OD) was at least twice that of the negative ...
Samples without glucose-6-phosphate (G6P) were used to control the specificity of the reaction. Parasite lysate was prepared by sonication of Saponin (0.01%) liberated trophozoite stage P. falciparum 3D7 parasites. Briefly, P. falciparum lysat...
So far, their edges, dopant heteroatoms and defects have been intensively explored as active sites for the hydrogen evolution reaction (HER) to split water. However, grain boundaries (GBs), a key type of defects in TMDs, have been overlooked due to their low density and large structural ...
