You synthesized Nylon-10,6, using interfacial polymerization. Draw a representation of what your experiment looked like. Clearly...
what is the theoretical yield for this experiment? ORGANIC POLYMERS: THE SYNTHESIS OF NYLON Nylon's outstanding characteristic in the textile industry is its versatility. It can be made strong enough to stand up under the punishment tire cords must endure, fine enough for sheer, high fashion hosiery, and light enough for parachute cloth and backpacker's tents. Nylon is used both alone and in blends with other fibers, where its chief contributions are strength and abrasion resistance. Nylon washes easily, dries...
Physics of the Human Arm If you have ever done bicep curls at the gym and looked at your arm in the mirror while you were doing it, you might have seen something like Figure 1 (plus or minus tanned skin and/or hair! Figure 1: Outside of arm lifting a weight using mostly the contracted bicep muscles We know what's going on under your skin from anatomy. The bicep muscles are attached via tendons to the top of your shoulder...
Draw the following sketches. “Sketch” means a drawing that clearly illustrates the concept(s) related to the question, but does not require you to use a computer or to do any calculations to draw. Be sure you clearly label the axes. (a) Sketch a production function (with one input) that implies economies of scale at low levels of output and diseconomies of scale at high levels of output. (b) What does the corresponding cost curve look like? Provide a separate sketch...
Extraction of solids: Experiment outlined below Draw a “roadmap” of the experiment, containing chemical structures and “layers” (organic and aqueous). This should contain the individual reactions occurring in each step, and show which layer the various components are present. Make sure you think about whether the acetaminophen, caffeine and aspirin are neutral, protonated or deprotonated. Preliminary separation obtain a sample (1.0g) of the mixture. weigh the sample and record it. this sample should consist of a 2:1:1 mixture (by mass)...
Draw the condensed structure of 2,2-dimethylbutane. b.) Estimate what the 1H NMR spectrum of 2,2-dimethylbutane is expected to look like. c.) Clearly label each proton environments and match each to its signal. d.) Be sure to include appropriate splitting. e.) Above each signal, include the appropriate integration.I need problem 1, part C answered.4-1.jpg
Experiment 7 In your Pre-Lab, you should draw the chemical reactions for the carbonyl tests using 2 butanone and benzaldehyde, summarize the functional group(s) that give a positive result and describe the appearance of the positive result. Locate the m.p. for the 2,4-DNP and semicarbazone derivatives for 2-butanone and benzaldehyde Dictionary of Organic Compounds or Handbook of Data ful For the Tollens' and

EXPERIMENT W12: ORGANIC STRUCTURES AND MOLECULAR MODELS 7. Build models of all possible isomers of CHCl, and then draw and name the Lewis Structure for each Isomers that differ in their relative geometry (or orientation) across a rigid double bond are called geometrie isomers. Circle your geometric isomers. Label each molecule as polar or non-polar. Certain physical properties of molecules, such as boiling point, are dependent on the degree of polanty of a molecule. What hybrid orbital is used by...

Experiment . the reduction of bencil (March 2020) Your name Sodium borohydride is a convert recent for the reduction of dehydes and ketones to 1" and 2 alcohols, respectively. The mechanism of the reaction - (below) is straightforward and is driven by boron's affinity for oxygen. In addition, given borohydride's remarkably low reactivity with OH groups under neutral and especially basic conditions, this reaction can be done in alcohol solvents. This means that (unlike LAH or Grignard reactions) no separate...
