- Penicillin heralded the dawn of the antibiotic age when it was discovered in 1928 and is now the most widely used antibiotic in the world. A membrane electrode was developed for the quantitative analysis of penicillin. The table above shows the data which were collected using a set of penicillin standards against saturated calomel electrode. An unknown sample produced a potential of 142 mV. A) Which served as the reference electrode? B) What is the molar concentration of penicillin in the sample?The material to be heated is in a long, cylindrical tube, and is viscous enough that any flow inside the tube can be ignored, i.e. the heating is by conduction alone). Also, consider the glass of the tube to be very thin so its thermal resistance can be ignored. The tube diameter is 1 cm and the properties of the material are the same those of water, given by 0.64 W/m*K, 1000 kg/m3, and 4180 J/kg*K, for thermal conductivity, density, and specific heat, respectively. The water bath temperature is 65 °C, and the initial temperature of the material is 27 °C. Without the agitation of the water bath, the heat transfer coefficient can be considered to be 128 W/m2*K. Considering the tube to be a long cylinder, how long does it take for the coldest point to heat up to a temperature corresponding to 99% of the total possible temperature increase? If the surrounding how water is agitated using a stirrer, leading to a considerably large surface heat transfer coefficient, how long does it…For the serial dilution, your stock solution must have a concentration of 3.5 mg/mL.

- The concentration ofacetylcholine (a neurotransmitter) in a sample can be determined from the pH changes thataccompany its hydrolysis. When the sample is incubated with the enzymeacetylcholinesterase, acetylcholine is converted to choline and acetic acid, whichdissociates to yield acetate and a hydrogen ion: In a typical analysis, 15 mL of an aqueous solution containing an unknown amount ofacetylcholine had a pH of 7.65. When incubated with acetylcholinesterase, the pH of thesolution decreased to 6.87. Assuming there was no buffer in the assay mixture, determinethe number of moles of acetylcholine in the 15 mL sample.What might happen if you omit potassium tellurite in using GCM?Guanosine (C10H13N5O5) in solution has a maximum absorbance at a wavelength of 275 nm.
