The double bonds in natural unsaturated plant fatty acids are always [choice1] and have [choice2] number of carbons.    

The two  lactic acid molecules on the left are starting a polymerization reaction with the goal to produce long chain PLA. What is missing in that box on top of the arrows? What problem would you expect for this reaction and how would you adress it?

Based on the table below, how much glucomannan would you be expect in this pine wood sample (report dry g glucomannan in 100g dry biomass). Please use a Glu:Man ratio of 1:3 for pine glucomannan. Glucose MW = 180, Water MW = 18.   g sugar released per100 g DRY Pine wood Glucose 44.00 Mannose 12.00 Xylose 6.19 Arabinose 0 Galactose 0 Klason lignin 28.1

 Below is the reaction for conversion of cellulose to Carboxymethyl Cellulose (CMS).i.)    Why the 1st step is treatment with NaOH. ii.)    What property did we introduce by adding the CH2COO- group to the cellulose? Think about why we did this reaction and what CMC is used for.   

This molecule will undergo mutarotation in aqueous neutral systems. What does it mean? What other possible structure(s) would this molecule be converted to?  

During the transesterification of triglycerides to biodiesel (methyl esters) with methanol and NaOH, what is the active species attacking the  C=O bond in the triglycerides?

Gasification…. select all answers that are true

Given the statements below, which type of processing it best describes. – Also called multiprogramming- Use of concurrent processing to simulate simultaneous execution of multiple programs even when using only a single CPU- Supports multiuser systems

To achieve better load-balancing, we may use the following configuration for clusters:
