OTHERMOMISTRY Calculating heat of reaction from bomb calorimetry data A student runs two experiments with a constant volume "bomb calorimeter containing 1000g of water (see sketch st right) First, a 5.000 g tablet of benzoic acid (CHCO,H) is put into the 'bomb" and burned completely in an excess of oxygen (Benzoic acid is nown to have a heat of combustion of 26.454/8) The temperature of the water is observed to rise from 24,00 C to 50,99 Cover time of 8.5 minutes Next, 5.260 g of acetaldehyde (CHO) are put into the bomb" and similarly compiletely burned in an excess or oxygen. This time the temperature of the water rises from 24.00 C to 52.26 C Use this information, and any other information you need from the ALEKS Data resource, to answer the questions Delow about this reaction A 'bomb calorimeter 2CH.06) 50,61) -- 400,() 41,06) Be sure any of your answers that are calculated from measured data are rounded to the correct number of ficant digits Note for advanced students it's possible the student did not do these experiments sufficiently carefully, and the valves you may not exactly match published values for this reaction exotherm endothermic neither 2 Is this reaction exothermie, endothermic, or ether If you said the reaction was thermic or endothermic calculate the amount of eat that was ned or absorbed by the reaction in the second experiment Calculate the reaction entro AW.
