Why does AgBr show both Frenkel and Schottky defects?
The radius ratio for AgBr is intermediate. Thus it shows both frenkel and schottky defects. The major defect in AgBr is the Frenkel defect. It has a rocksalt structure i.e. CCP lattice of of Br with atoms of Ag occupying all octahedral holes.Ag moves from octahedral to tetrahedral sites causing only cations to precipitate. Schottky defect arise due to missing of ions from their lacttice point and frenkel arise when the mmissing ions occupy interstitial sites. in AgBr, ag+ ion is small in size and when removed from lacttice point they can occupy interstitial site and therefore show both frenkel and schottky defect. SCHOTTKY Defect in AgBr is exhibited due to precipitation of both Cations and Anions.
Where do reactants bind to the enzyme?
They bind in the active site.
What are the two bonding sites of tRNA on the ribosomes?
tRNA has two binding sites on the ribosome first one is A-site (aninoacyl -tRNA binding site), and second one is P-site (peptidyl-tRNA binding site) and E-site (Exit site)
The part of the enzyme into which the substrate fits is called the?
isomer position
How might an amino acid change at a site distant from the active site of the enzyme alter the enzyme's substrate specificity?
The alteration of an amino acid on a site other than the active site will: change the shape of the protein.
What are the differences between the Frenkel and Schottky defects?
A Schottky defect is when 2 oppositely charged ions leave their normal lattice positions forming 2 vacancies in the lattice structure. This contrasts to a Frenkel defect, where 1 ion simple moves from it's normal lattice position to an interstitial site (tetrahedral/octahedral hole).

Is there any selection rule for choosing elements in A site of a perovskites having ABO3 structure?
Generally speaking, the A sites are usually occupied by the larger cation; in the case of the prototypical perovskite, CaTiO3, the larger Ca(II) ion occupies the A site while the smaller Ti(IV) cation occupies the B site (the M in the MO6 octahedra).
Where can I find corner TV stands in New Hampshire?
Kmart, Wal-Mart and Target all have things like that. Also, for a larger selection check online at Amazon. You will have to pay shipping, but you will have a larger selection. Even check Wal-Mart and Targets online site will give you are larger selection. They usually offer site to store free shipping.
How do the city differ from the village?
Cities are larger and are actually a declared society whereas a village is small and an unofficial site
What is the special sites on mars?
a good site would be Olympus Mons, a volcano 3x larger than mount Everest!
Is there a dating site where girls can find big guys?
Just join a regular dating site and specify you are looking for larger guys. Mavenrestin.com has a profile options to show exactly what type of guy you are looking for
What is 45mm?
45mm= 4.5 cm45mm = 0.045mThese are simple numbers, but if you have larger numbers go to google and use convert units site.
What is the preferred site for a blood draw?
The usual location is the inside of the elbow, where veins are near the surface and larger than the ones found in the wrist.
What is the number of spheres in hexagonal close-packed crystal structure?
The hexagonal structure of alternating layers is shifted so its atoms are aligned to the gaps of the preceding layer. The atoms from one layer nest themselves in the empty space between the atoms of the adjacent layer just like in the fcc structure. However, instead of being a cubic structure, the pattern is hexagonal.The hcp structure has three layers of atoms. In each the top and bottom layer, there are six atoms that arrange themselves in the shape of a hexagon and a seventh atom that sits in the middle of the hexagon. The middle layer has three atoms nestle in the triangular "grooves" of the top and bottom plane. Note that there are six of these "grooves" surrounding each atom in the hexagonal plane, but only three of them can be filled by atoms.SAMPLE:· Nickel Arsenide Structure s based on a distorted hcp array of Arsenide anions. By contrast with the wurtzite structure, however, which is also of formula AB, the cations now occupy all the octahedral sites rather than half the tetrahedral holes. There is one octahedral hole for each hcp lattice site, and so the AB stoichiometry is preserved.· Titanium Oxide, TiO2. he anions occupy the hcp lattice, and the cations occupy half of the octahedral holes.LutetiumThalliumTerbium
How can I get my site to appear on the first page of Google to reach a larger target audience and more sales and profits?
If you want your website to appear on the first page of Google. Because it is of very high importance to reach a larger target audience and more sales and profits If so then I encourage you to go to this site and be impressed by the suggestions they have on this matter CLICK HERE: bit .ly/3kMKDtX (cancel the space)
Is there an useful website that has lyrics for most songs?
I would recommend "Googling" the lyrics to a song, because it will give you a larger search than a specific site would.
