Energy output of Bioethanol and Industrial Ethanol Essay

AimThe aim of this investigating is to determine which of the two derivatives of ethanol releases more null, Bioethanol or Industrial ethyl alcohol. guessworkThe main compound in both alcohols has the same chemical formulae C2H5OH, and the former(a) compounds are unknown therefore the Energy output cannot be calculated exactly by using standard bond enthalpies. However, as the main compound is known and the same for both ethanols the susceptibility output should be very similar. then the difference in energy output only depends on the compounds which are blended to the alcohols.frame-up Thermometer metallic element can x2 Draught shield x4 Gloves Safety spectacles Heat-resistant mat withdrawal card 100cm3 measuring cylinder x2 Spirit burner Clamp stand balance wheel MatchesSubstances E100 Bioethanol Industrial Ethanol WaterMethodThe idea to do the examine the way described is due to knowledge from past experiments and the IB textbook.Follow these travel 10 times, five time s for each alcohol.Step 1 legal community 50cm3 of alcohol in a measuring cylinderStep 2 Weigh and temperament the empty kernel burnerStep 3 meet the 50cm3 of alcohol in the spirit burnerStep 4 Weigh and record the filled spirit burnerStep 5 Measure 100cm3 of Water in a measuring cylinderStep 6 Fill the pee into the metal canStep 7 Set up the Apparatus as displayed (1 draught shield in each direction, south, north, west and east, forming a box around the apparatus assure there are 2cm of position between the bottom of the metal can and the cotton plant fiber plant wick)Step 7 Record the initial temperature of waterStep 8 Light the cotton wick of the spirit burnerStep 9 Record the temperature every 15 seconds until the cotton wick loses its flameStep 10 Weigh the spirit burner with the remaining alcohol to calculate how many grams of alcohol have been utiliseVarables Temperature Temperature of Water lead be measured before every experiment. The satisfying experiment takes place at room temperature. Volume of Water 100cm3 mass of alcohol 50cm3 filled in spirit burner. The mass will be measured before and after the experiment to figure how much has been used. term record every 15 seconds Concentration of alcohol 1M Surface plain of metal can which flame is heating up same cans will be used and positioned at same place above the cotton wick to keep this constant. Length of cotton wick 0.5cm Distance from cotton wick to bottom of metal can 2cmHazard Warnings Industrial Ethanol Highly flammable. Therefore wear gloves and safety spectacles Bioethanol Highly flammable. Therefore wear gloves and safety spectaclesChemistry HL Plan of investigating
