homogeneously and precipitate, because in the tertiary system water is further preferred to from hydrogen bond with NMMO than cellulose [288, 292, 314]. Ballooning and swelling modes of cellulose dissolution is more efficient for biogas production, while for ethanol production pretreatment with 85% NMMO leads to a better lignocellulose bioprocessing

1 in 8 deaths of Australians under 25 years is related to alcohol consumption. Fellow year 12 and Mrs Thomas there is much research showing the benefits of raising the legal drinking age in Australia from 18 to 21. I believe it is the right thing to do for the good of our health and the good of our futures. Young people are particularly vulnerable to the effects of heavy drinking. Excessive alcohol consumption affects how our young brains develop. Studies have shown that alcohol consumption negatively

Reactions 1. Reduction: Aldehydes and ketones may be reduced to 10 alcohols and 20 alcohols, respectively using the reducing agent sodium tetrahydridoborate, NaBH4. (Water or ethanol is used as a solvent.) (a) Reduction of Ethanal CH3CHO + 2[H] NaBH4 in water CH3CH2OH (b) Reduction of Propanone CH3COCH3 + 2[H] NaBH4 in ethanol CH3CH(OH)CH3 Regarded basically as the addition of H2 across the C=O double bond.

reactions * Alcohol dehydrogenase oxidises ethanol to acetaldehyde - hepatotoxic so is then oxidised by aldehyde dehydrogenase to acetate * NAD+ oxidised to NADH - increases lactate conc - slows down krebs cycle - less ATP made DISULFIRAM Aldehyde dehydrogenase inhibitor - leaves acetaldehyde in system that produces convulsive effects and hot flushes - puts drinkers off drinking - used as therapy to treat chronic alcoholism * Amount of ethanol oxidised depends on NAD+ availability

Drink and Drive I understand your concern with drinking and driving this can be very deadly. Many college student can be influence every day that can cause an issues with thousand lives that will be lost.

generally unreactive with most substances. 1butanol is an alcohol so it will undergo many reactions such as dehydration with a sulfuric acid catalyst, oxidation with an oxidizing agent [O], it will form esters with a carboxylic acid etc. d) ethanol and 1-decanol: • ethanol has a very small alkyl group (2 C) so it is completely miscible in

Reflection - Penn State Student Drinking Behavior The first two observations I made about the survey data were that college age drinking habits have not changed from year to year in a drastic way and students still tend to experience drinking and partying early in their college studies. About age 18 to 19 students transition from high school to this huge opportunity to be out from under the parental “house rules” for the first time in their lives. According to the Pulse survey, 83% of the
