13. The generic resonance structures A and B can be drawn for all carboxylic acid derivatives, yet their contribution to the overall resonance hybrid differs for the derivatives. Explain why the contribution of resonance structure to the hybrid is: a. Poor for an acid chloride or bromide. b. Greater for an amide than an ester. 14. Listed are frequencies for the carbonyl stretching modes in each molecule's IR spectrum. Explain why one carbonyl absorbs IR at a higher frequency than...

1. Introduction In recent years, nanoclays have been the object of particular interest for many scientists and researchers in chemistry, physics, engineering and biology due to their excellent properties as well as their sustain- ability [1-3]. For instance, they represent the starting point to the de velopment of smart materials for drug delivery (4-9), food packaging [10-12), environmental remediation and wastewater treatment [13], cultural heritage [14–17and...

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...
