You are a lab assistant preparing a solution of known concentration of phosphorus. You have pure trisodium phosphate (Na3PO4) towork with, and you weigh out 0.328 g of the solid and add it to a 1.00 L volumetric flask which is mostly full of DI water; you thenfill to the mark with DI water.

After graduating from your PhD, you are now working as a post-doctoral researcher in BASF , the world’s largest multinational chemical company. The management of your R&D department decided to look at the potentiality of chloroform-methanol mixture in removing the lipids of various biological systems. Your boss, a senior scientist at your department, thinking about the hydroxyl group on the alcohol and thet hree chlorines on the CHCl3 , suggested that the mixture is probably non-ideal. Being one of her brightest colleagues, she then tasked you to graph the partial molar enthalpies of the chloroform methanol mixture as a function of mole fraction. Ardently, you accepted the challenge and went back to your office. After several hours of searching, you finally come up with enthalpy of mixing data at 50oC fort his mixture (See the picture). Please provide the graphs that the boss has asked you for. Put both curves on the same graph. Note: provide your excel file for this
) PLA, a polyester-based synthetic polymer, decomposes in our body fluid and separates into its constituent acids and alcohol. This acid in the body can cause inflammation. What would you recommend to overcome this disadvantage? b) The late decomposition of PLA, which is a biodegradable and hydrophobic polymer, in body fluid may create a disadvantage in applications where faster degradation is desired. What would you suggest to do to resolve this situation? Please explain.
