Is NaClO3 is ionic and is it an acid or base? Why is it more likely that Strontium will lose electrons rather than gain electrons? How are OH- ions produced during addition of HCN to aldehydes and ketones? What are dative covalent b...
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...
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...
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....
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...
Covalent and organic compounds While H2 is not very reactive under standard conditions, it does form compounds with most elements. Hydrogen can form compounds with elements that are more electronegative, such as halogens (F, Cl, Br, I), or oxygen; in these compounds hydrogen takes on a parti...

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-...
A convenient laboratory preparation involves the reduction of bromine or iodine with red phosphorus and water: (22)2P+6H2O+3X2X=BrorI→6HX+2H3PO3 (23)H3PO3+H2O+X2→2HX+H3PO4 A reaction analogous to Eq.(18)may be employed if the acid is nonoxidizing (e.g., H3PO4), andsodium br...
