Why AgBr shows both frenkel and schottky defect?
AgBr can exhibit both Frenkel and Schottky defects due to the presence of both cation (Ag+) and anion (Br-) vacancies in its crystal structure. Frenkel defect occurs when a cation occupies an interstitial site, while a Schottky defect involves the simultaneous absence of a cation and anion from their respective lattice sites. The relative sizes of the cation and anion in AgBr make both types of defects possible.
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.
Why AgBr shows both frenkel and schotky defect?
When the both the cations and anions are absent from the crystal lattice it is called Schottky defect. This defect is shown when the anions and cations have comparable size. The Frenkel defect is shown by ionic molecules when their is a large difference in the size of anions and cations. The smaller anions are very much mobile and they occupy interstitial site. AgBr has cations and anions with comparable size and hence it shows Schottky defect but the Ag+ ion is very much mobile and it easily occupies interstitial place getting dislocated from its original place, that's why the ionic crystal AgBr shows both Schottky and Frenkel defects.
What are the different types of congenital heart disease in adults?
The different types of congenital heart disease in adults are - Atrial septal defects, both secundum and primum, with closure often achieved with outpatient catheter-based techniques. - Ventricular septal defects. - Coarctation of the aorta. - Valvular defects. - Tetralogy of Fallot.
What two types of defects does a cancerous cell possess?
Cancerous cells can have both genetic defects, such as mutations in key oncogenes or tumor suppressor genes, and functional defects, such as uncontrolled proliferation and evasion of cell death mechanisms. These defects allow cancer cells to grow uncontrollably and spread to other parts of the body.
How does zim like dib?
He doesn't but if you are a ZADR supporter then I guess you could go with that they are both defects of their species and even defects need love.
Calculate the molar solubility of AgBr in a 3.0 x 10-2 M silver nitrate AgNO3 solution?
AgBr + Ag(NO)3 ----------> Ag+ + Br- Disregard Ag(NO)3 b/c of the common ion Ag and the fact that (NO)3 is a spectator ion. You use the Ksp of AgBr from the index in your book that equals 5.0*10^-13 If you look at your above equation, Ksp = [Ag] [Br] You know Ksp = 5.0*10^-13 You have also been given the concentration of Ag from Ag(NO)3 = 3.0*10^-2. You use this number because remember NO3 is always a spectator ion so [Ag] will equal the [Ag(NO)3] You equation should look like this. (Forget about doing the I.C.E on this one. Its not necessary. 5.0*10^-13-= [3.0*10^-2] [Br] Simply solve for [Br] by dividing 5.0*10^-13 by 3.0*10^-2. [Br] = 1.66*10^-11. Round for sig figs to = 1.7*10-11
Can you get an Army medical waiver if you have birth defects in both arms?
what are the birth defects? Can you still function normally? if so I'd say yes; if it is a handicap most likely no.
What is done during a cardiac catheterization to confirm septal defects?
To confirm septal defects, a catheterization measures oxygen content on both the left and right sides of the heart.
What is the difference between vacancy and self interstitial crystalline defects?
the simplest of the point defects is a vacancy or vacant lattice site ,one normally occupied from which atom is missing is called vacancy a self-interstitial is an atom from a crystal that is crowded into an interstitial site , a small void space that under ordinary circumstances is not occupied.
What is the major and minor quality of 5000pices garments at AQL 1.5?
At an Acceptable Quality Level (AQL) of 1.5 for a batch of 5,000 garments, the major quality defects are those that significantly affect the garment's functionality or aesthetic, such as incorrect sizing, severe stitching issues, or fabric flaws. Minor quality defects are less impactful and might include minor stitching irregularities or slight color mismatches. For a 5,000-piece lot, AQL 1.5 typically allows for a maximum of 75 defects (major and minor combined), with a stricter limit on the number of major defects. Thus, maintaining quality standards is crucial to minimize both types of defects.
How many babies are born in the US each year with birth defects?
Approximately 120,000 babies in the United States are born each year with birth defects. These defects can range from mild to severe and may be caused by genetic factors, environmental exposures, or a combination of both. Early detection and intervention can help manage the effects of birth defects.
