Answer: Since most of the dissolved CO2remains as CO2 molecules, Ka1(apparent) has a much larger denominator and a much smaller value than the true Ka1. The bicarbonate ion is an amphoteric species that can act as an acid or as a base, depending on pH of the solution. At high pH, it dissociates significantly into the carbonate ion (CO2−3):
Explanation: In organisms carbonic acid production is catalysed by the enzyme, carbonic anhydrase. CO2 is a potent electrophile having an electrophilic reactivity that is comparable to benzaldehyde or string α,β-unsaturated carbonyl compounds. However, unlike electrophiles of similar reactivity, the reactions of nucleophiles with CO2 are thermodynamically less favored and are often found to be highly reversible. Only very strong nucleophiles, like the carbanions provided by Grignard reagents and organolithium compounds react with CO2 to give carboxylates. In metal carbon dioxide complexes, CO2 serves as a ligand, which can facilitate the conversion of CO2 to other chemicals. The reduction of CO2 to CO is ordinarily a difficult and slow reaction:

A free body diagram is used to calculate static and dynamic forces acting on an object. In other words, a free body diagram is the starting point to develop a mathematical model to find and calculate various forces acting on a body.

Explanation:
The lattice structure of Lithium Fluoride (LiF) is comprised of positively charged lithium ions (Li+) and negatively charged fluoride ions (F-) that a linked together by ionic bonds.
The crystal structure of LiF corresponds to that of a face centered cubic (FCC) lattice with Li+ and F- ions occupying the lattice points in the unit cell.
Answer:
Explanation:
An ionic bond is produced between metallic and non-metallic atoms, where electrons are completely transferred from one atom to another. During this process, one atom loses electrons and another one gains them, forming ions. Usually, the metal gives up its electrons forming a cation to the nonmetal element, which forms an anion.
Lithium fluoride is a chemical compound formed through a chemical bond of formula LiF. The electronic configuration of Li is 1s12s1 and that of fluorine is 1s12s22p5. When these atoms come into contact, the 2s1 valence electron of the lithium is transferred to the F atom.
Ionic solids can crystallize in various types of networks, depending on the size of the ions that form it and the charge they possess.
The solid NaCl has a crystalline structure, in which each Na + ion is surrounded by six chloride ions in an octahedral geometry. Therefore, it has a coordination (6: 6) whose numbers indicate how many neighbors surround each ion. The number on the right indicates the neighbors of Na +, while the one on the left, those of Cl–. The structure is based on a compact cubic packing (centered on the faces) of the anions and in which the cations occupy all the octahedral holes. The structure can also be seen as a compact cation packing structure with the anions occupying the octahedral holes. In each unit cell ions of one type occupy the vertices and centers of the faces of the cube while those of the opposite sign are located in the centers of the edges and in the center of the cube.
