a domestic, renewable fuel for diesel engines derived from natural oils like soybean oil, and which meets certain requirements specified by international standards correct answer: general definition of biodiesel a fuel comprising of long-chain fatty acid methyl esters (FAMEs) derived from vegetable oils or animal fats, designated B100 and meeting standard requirements correct answer: technical definition of biodiesel what are the three commercial methods for making fatty acid methyl este...

What is biodiesel correct answer: a fuel comprising long-chain fatty acid methyl esters (FAMEs) derived from vegetable oils or animal fats, designated B100 and meeting standard requirements. What methods can be used to make fatty acid methyl esters (FAME's)? correct answer: -Base-catalyzed transesterification -Acid-catalyzed esterification -Saponification of the oil to yield free fatty acids, followed by acid catalyzed esterification What are fatty acids? correct answer: carboxylic ...

biodiesel correct answer: comprised of long-chain FAMES(fatty acid methyl esters) three methods for production of Biodiesel correct answer: -catalyzed transesterification 2. acid-catalyzed transesterification 3. saponification followed by acid-catalyzed transesterification method used in experiment correct answer: base-catalyzed transesterification a-linoleic acid correct answer: 17 carbon chain three double bonds linoleic acid correct answer: 17 carbon chain two double bonds...

What are saturated vs unsaturated fatty acids? correct answer: •Saturated fatty acids have no C=C bonds (their C's have max # of Hs) •Unsaturated fatty acids have one or more C=C bonds (monosaturated = one double bond) (polyunsaturated = more than 1 double bond) •Z (cis) are naturally occurring double bonds; E (trans) are artificial double bonds How is biodiesel produced commercially? Which method is predominant? correct answer: ***1) Base catalyzed transesterification of oil with ...

Unsaturated fatty acids - have one or more C=C bonds Saturated fatty acids - Have no C=C bonds What are the ways that biodiesel is produced commercially? Which method is the predominant method? - 1) Base-catalyzed transesterification of the oil with methanol and one used in lab. 2)Acid-catalyzed esterification of the oil with methanol 3) Saponification of the oil to yield free fatty acids, followed by acid catalyzed esterification. Match the products and catalyst for the following tran...

Genetics Module 2 Exam With Questions and Answers 100% Solved What does it mean to say that double-stranded nucleic acids are antiparallel? - answer(Marked off)It means one strand is 5'-3' and the other is 3'-5'.
