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...

1. You set up a chemical reaction with two materials, but only one of which shows up by TLC (Compound A, Rf = 0.75). Your product is supposed to have an Rf of 0.5 in the same eluent. Draw three TLC plates that you expect to see at these times: 1) at beginning of reaction, 2) halfway through reaction, 3) when reaction is done. Try to keep the TLC plates no more than 5cm in height, and just label the...

Learning Goal: Develop problem-solving skills wing chemical equilibria and oplying Le Chatter's principle Solving problems with chemical equilibrium If you know the basic principles of chemical equilibrium, you can analyze and predict reversible reactions. To analyze any reversible reaction, follow these problem-solving steps: 1. Identify the reactants and products for the given chemical reaction. 2. Draw a diagram of the reaction to better understand what is happening 3. Identify how increasing or decreasing a product or reactant stresses the equilibrium...
