95% ethanol as the solvent‚ to calculate the amount of sulfanilamide that was recovered‚ and to determine the purity of the final product. Introduction In this experiment‚ recrystallization will be the method used to purify the solute sulfanilamide using ethanol as the solvent. Based on the solubility curve on the solubility versus temperature graph‚ the ideal solvent will allow the solute to be soluble at higher temperatures and insoluble at lower temperatures‚ thus making ethanol an excellent

year. There are many options America could use to end this war on oil. Some of them include the use of ethanol‚ hybrid cars‚ and nuclear power plants. We do use some of these‚ but perhaps we need to expand their use instead of looking to the Middle East to continue to supply our needs. However‚ we have not taken the time‚ nor initiative to research some of these ideas further. For instance‚ ethanol as a fuel is available in some

order to use the fuel [4]. Ethanol Ethanol is a biofuel used to run engines that originally used petrol. There are a few modifications done to the vehicle so that it can run efficiently on Ethanol. A vehicle with these modifications is classified as an FFV or a Flexible Fuel Vehicle [5]. Brazil is one of the countries that have embraced this technology into their system becoming the second largest producer of ethanol in the world by producing sugarcane based ethanol [6]. Through these developments

Why does alcohol consumption increase urine production? A.alcohol must be eliminated by excretion B.alcohol inhibits ADH causing diuresis C.alcohol increases the production of ANH causing diuresis D.alcohol increases the collecting duct’s permeability to water 8. Where is the glomerular apparatus located?

In this investigation I will be burning alcohol ’s to heat up a can of water. I will be burning four alcohol ’s‚ methanol‚ ethanol‚ propanol and butanol. The aim is to find out how much energy is produced when burning these alcohols. Alcohol ’s react with oxygen in the air to form water and carbon dioxide. The reaction that is involved in burning alcohols is exothermic because heat is given out. From this reason the reactant energy is higher than that of the product. The energy is given out when

today product and services are both key to the survival of mankind. Depending on the demand from consumers‚ companies will see an increase or decrease of the items they produce or the service rendered. In the article of trends in US gasoline and ethanol use and petroleum production and imports these items will be looked at; as well as a discussion of the fundamentals of microeconomics. First‚ in order to understand what the fundamentals of microeconomics are‚ there must be a clear understanding

should be saturated‚ having single bonds to three other atoms.[1] An important class of alcohols are the simple acyclic alcohols‚ the general formula for which is CnH2n+1OH. Of those‚ ethanol (C2H5OH) is the type of alcohol found in alcoholic beverages‚ and in common speech the word alcohol refers specifically to ethanol. Other alcohols are usually described with a clarifying adjective‚ as in isopropyl alcohol (propan-2-ol) or wood alcohol (methyl alcohol‚ or methanol). The suffix -ol appears in the
