in the lab we are doing the chemoselective reduction of 3-nitroacetophenone using sodium borohydride , a question our lab demonstrator asked us to do for the lab report was to draw the mechanism of reduction with NaBH4 but show all steps. i.e 1 x NaBH4 reduces 4 x carbonyls and not to stop when one mole of carbonyl is reduced and to also show alkoxide salts formed at each step...

We performed a synthesis of methyl diantilis lab. The first step
involved a Sodium Borohydride Reduction of
3-Ethoxy-4-hydroxybenzaldehyde (Ethylvanillin) shown below.
The next step of the experiment involved Etherification of
3-ethoxy-4-hydroxylbenzyl Alcohol using one of four alcohols
(methanol, ethanol, 1-propanol, or 2-propanol). The alcohol I used
was methanol. The reaction is predicted below.
Below is the NMR sample for my product with the integration and
ppm for each peak displayed.
Based on this information, answer the following questions.

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...
