Structural characterization of Streptococcus pneumoniae capsular polysaccharides (CPS) is a prerequisite for unraveling both antigenic and genetic relationships that exist between different serotypes. NaHCO3. When finding the resonance structures, I said there are 2, but the exam solutions state 4, which was confirmed by internet images such as this: However, I see no real difference btween structures 1 and 2, and 3 and 4. Use The Best Resonance Structure For Phosphate Ion To Determine This Hybridization. Share your thoughts, experiences and the tales behind the art. Phosphate ester flame retardants are composed of a group of chemicals with similar properties but slightly different structures. Furthermore, the ion you've quoted does not exist. Glass structure comprising (0–20) mol% Al2O3–(20–40) mol % Ag2O-and 60 mol % P2O5 was examined using a 27Al, 31P MAS- NMR and FTIR spectroscopy. Calculate the average bond order for a P−O bond (such as the one shown in blue) in a phosphate ion. Answer Chapter 3 Thermodynamics of Biological Systems Biochemistry 5th Topics. But all of the bonds in PO4^3- are identical. In general, molecules with multiple resonance structures will be more stable than one with fewer and some resonance structures … Hybridization = 1/2 { no.of valence ele. Get your answers by asking now. So, there is no multiple bond in the molecule. What is the mole fraction of C2H5OH in a solution that contains 46.00 g of ethanol, C2H5OH and 64.00 grams of methanol, CH3OH [0.3333]. In all of these the P has a formal charge of 0 and one oxygen is also 0.

Therefore, P = 6n + 2 – V = 6 * 5 + 2 – 32 = 0. Only one of two possible resonance structures are drawn above for dihydrogen phosphate. Ideally, the formal charges should be as close to zero as possible. Phosphate glasses can be made with a range of structures, from a cross-linked network of Q 3 tetrahedra (vitreous P 2 O 5) to polymer-like metaphosphate chains of Q 2 tetrahedra to ‘invert’ glasses based on small pyro- (Q 1) and orthophosphate (Q 0) anions, depending on the [O]/[P] ratio as set by glass composition. Join Yahoo Answers and get 100 points today. Phosphate esters have found numerous industrial applications due to their overall stability, especially in the presence of oxygen [].The general structure, shows the fully oxidized phosphorus at the core.The ability to exchange oxygen for sulfur and to easily include a variety of substituent groups has led to a wide range of applications. 4 4.
