- Complete the equation, using appropiate notations and fromulas: 410Be=?+510BPlease help me the the lewis and resoance structures. Draw them out please!! A bond between CO and M, where M is a lewis acid, which forms M-CO. Where M does not have no lone pairs, has one lone pair and two lone pairs.Please i want the answe to question below.
- Hoping for solutions since I’m having a hard time with this. Pls skip if unsure or not willing to answer the subitems (these are all connected for one item). Thanks in advanced. Kriel just discovered a new protein, Krielase and for it not to unfold and lose its function, he realized that the protein needs to be constantly immersed in a pH = 6.50 solution. He is therefore interested in preparing a 50 mL 0.08 M pH = 4.50 buffer to contain the protein. He listed down the pure acids available to his disposal, and also looked for their acid dissociation constant (Ka) values. Acid Name Ka1 Ka2 Ka3 Nitrous Acid (HNO2) 4.00 x 10-4 N/A N/A Acetic Acid (CH3COOH) 1.76 x 10-5 N/A N/A Ascorbic Acid (HAsc) 7.90 x 10-5 1.60 x 10-12 N/A Phosphoric Acid (H3PO4) 7.52 x 10-3 6.23 x 10-8 4.28 x 10-13 A. Identify which weak acid system is best to use in preparing the buffer? Why? B. Identify the species which will make up the buffer system?…Really hoping for solutions since I’m having a hard time with this. Pls. skip if unsure or not willing to answer the subitems (these are all connected for one item). Thanks in advanced. When the compounds analyzed by Robrob were passed on to the next test, anotherscientist, Kikoko, needed to determine the molecular weight of the active compound. They created a solution with a concentration of 20.0%w/w from the solid active compound and the solution had a density of 1.40 g/mL. From this solution, 10μL was taken and mixed with 190μL of reagent and water. It was analyzed and showed a concentration of 5x10-4 M compound.a. What is the concentration (in molarity) of the 20%w/w solution? b. Why was the concentration of the solution expressed as %w/w initially? c. What is the molecular weight of the active compound?Can you please answer these and give me an explanation.
