I replied to the post labled Dr.Bob with what I came up with which is the same answer I derived from my own thought process. Even after drying, the, nylon was likely quite wet and, given the high density of water, this likely explains our yield, Our final product after drying for 15 minutes was a white fabric-like, product. Application:It can be used as the workpiece when the Nylon 610 is under the condition of light load, appropriate temperature, humidity easily changes, etc. This is apparently a thing now that people are writing exams from home. Explain. -any disruption of the interface will diminish the yield of nylon and cause it to form a blob. Why don't objects get brighter when I reflect their light back at them? On the other hand, the experimental CH 4 yield obtained from experiment M1 was about 76% of the theoretical CH 4 yield (526 mL/gVS added) calculated by Eq. Tight supply of nylon 6,6 has made it a precious commodity. To the best of my understanding, it's adipoyl chloride reacting with 1,6-hexanediamine that forms the nylon 6,6 polymer so would that mean adipoyl chloride is the limiting reactant and I need to use the mol to mol ration between adipoyl chloride and 1,6-hexanediamine in order to find the theoretical yield? Percentage yield is 94.1% Therefore, What could a smart phone still do or not do and what would the screen display be if it was sent back in time 30 years to 1993? What is Screen Printing?
