In covalent bonds, is it possible for an atom to share both of the electrons? Which bond is stronger, ionic or covalent? What is the relationship between common ions and the number of electrons available to react? How does the column ...
The marked difference in stability of ionic and covalent azides is sometimes explained in terms of their structural differences. For example, the azide ion,N3−is a linear triatomic species that has 16 valence electrons, and it has three contributing resonance structures that can be shown as fol...
hypotension, andcirculatory collapsemay occur as a result of the ingestion of concentrated corrosive iodine solutions. Severe burns may occur fromdermal exposure. Burns have been associated with symptomatichypocalcemiaandmyoglobinuriawithoutrhabdomyolysis. Systemic toxicity could result in acute hepatic injury....
biomedicine, device, sensing, and printing arenas. However, covalent organic frameworks are generally not dispersible in common solvents resulting in the poor processability, which severely obstruct their application in practice. In this study, we develop a convenient top-down process for fabricating sol...
What is the strongest type of intermolecular attractive force present in dimethylamine, CH3NHCH3? a. ionic b. ion-dipole c. hydrogen bonding d. dipole-dipole e. dispersion forces What is the strongest intermolecular force exhibited in each? a. Covalent molecules b. Ionic compounds c. Polar c...
In ionic compounds, hydrogen can take the form of a negative charge (i.e., anion) where it is known as a hydride, or as a positively charged (i.e., cation) species denoted by the symbol H+. The H+ cation is simply a proton (symbol p) but its behavior in aqueous solutions and ...
The discovery of iodine in 1811, and Gay-Lussac's subsequent work on the acidity of hydrogen iodides, and his confirmation of Berthollet's earlier work on hydrogencyanidegave further support to this conclusion. 1811年碘的发现,以及盖-吕萨克随后对碘化氢酸性的研究,以及他(盖吕萨克)对贝托莱早期关于...

Crystalline porous molecular frameworks formed through intermolecular hydrogen bonding are often called hydrogen-bonded organic frameworks (HOFs) by analogy to metal organic frameworks (MOFs) and covalent organic frameworks (COFs). Although the origin may go back to the 1960s, HOFs have recently been ...
The composite electrolyte in the electrolysis cell reaches an ionic conductivity of 0.572 S cm−1 in the SOEC mode. The excellent hydrogen production performance proves that this new type of electrolysis cell with lithium compounds as electrodes is a promising and potential proton conductive low-...
