crystallize using ethanol and water. I chose these solvents based on part C of the experiment (table 1.1). The compound is too soluble in ethanol but too insoluble in water. Benzoic acid is a polar compound in comparison with ethanol which is a less polar compound. However at low temperatures benzoic acid is insoluble in water. Compounds are soluble in solvents with the same polarity‚ like dissolves like. Table 1.1 Benzoic Acid solubility Dissolve Heat Ice H2O No No No Ethanol Yes Yes Yes Hexane

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

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

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

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

I was the meanest‚ richest and smartest boy in my Primary Four class. Being a notorious bully‚ students cowered at the mere mention of my name. Without any reason‚ I would start bullying other students. I always had a bag of tricks up my sleeves‚ so my ‘attack’ on my ‘victim’ would come unexpectedly. I always had a sense of satisfaction after successfully bullying a student. It was like another feather in my cap. Others’ misery was my happiness. On one typical Monday recess‚ I caught sight of
