Alcohol Abuse By: Rian Geraldine S. Alberto Alcohol • • • • Alcohol is a drink containing ethanol It is a lipid that is highly water soluble A psychoactive drug that has a depressant effect. Distribution: Ethanol is distributed equally in all body tissue according to water content. • Metabolism: A healthy body can metabolize 15ml of alcohol/hour • Alcohol is metabolized by the liver but 10% is excreted unchanged in the breath‚ sweat and the urine Metabolism of alcohol Alcohol Aldehyde

Abstract Separation of the compound ethanol from alcoholic beverages‚ such as vodka‚ involves the process of distillation. Distillation is the separation of volatile substances mixed with nonvolatile substances by boiling the mixture to alter the phase of the volatile substance. The researchers used the simple distillation set up to conduct the experiment. 25 ml of The Bar Vodka was used and 7 ml of distillate was collected before a temperature of 95 degrees Celsius was reached. Collected distillate

molecular mass increases so does the enthalpy of combustion. The alcohols that I intend to use throughout this investigation are the following 6 alcohols: Ø Methanol - CH3OH solvent; fuel; manufacture of organic chemicals; denaturing ethanol straight chain alcohol. Ø Ethanol - (CH3CH2OH) ethyl alcohol; grain alcohol. A colorless‚ flammable liquid produced by fermentation of sugars. Straight chains. Ø Butane - CH3CH2CH2CH3‚ colourless‚ with a characteristic natural odor Ø Pentan-1-ol -straight chains

EXPERIMENT 5 SEPARATION OF A MIXTURE INTO ITS COMPONENTS BY FRACTIONAL CRYSTALLIZATION Introduction: Fractional crystallization is one of the experimental techniques used to separate or purify mixture. Fractional crystallization makes use of the differences of solubility to separate the components of a mixture. Goals: Applying fractional crystallization to separate a mixture of salicylic acid and copper sulfate pentahydrate into its components. Calculate the percent of salicylic

commonly known as baker’s yeast‚ is an key ingredient used mainly when baking bread or making alcoholic beverages. The main role of the yeast is to convert the sucrose into carbon dioxide (CO2) and ethanol. For example‚ when baking bread‚ the yeast ferments the sucrose within the dough and so CO2 and ethanol is released‚ causing the bread to rise and expand. It does this using enzymesAlso‚ during this fermentation process‚ because CO2 is released‚ it starts to form foam and that is why‚ for example‚
