3) Which semicarbazone is colourless and which is yellow. Why do
they differ in this property? In general, what gives a compound
colour? (Isn’t chemistry cool?)
Introduction Many reactions can take more than one course but the preferential formation of only one of the possible products may be attained by a judicial choice of the reaction conditions. In general, the 1 of 5 CHEM-2300 F19 Experiment 6 formation of a product is controlled by thermodynamic (differences in relative potential energies...

Organic chemistry. Can you please provide answer to this
question.
1. There are various alkene constitutional isomers of the molecular formula C6H8 (two degrees of unsaturation). A few of those isomers (compounds A-F) were reacted under vigorous oxidation (with H3O+ and KMnO4) to yield specific products. Please provide the correct structure of the reactants and products in the corresponding boxes that fit the appropriate description. Draw dashes and wedges, where necessary, to show stereogenic centers. Note: you can assume that...

4) There are 3 different N atoms in the semicarbazide, and yet
only one of them is the site that does the nucleophilic attack. Why
is that N atom most reactive? Describe using structures.

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...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
