A student runs two experiments with a constant volume "bomb calorimeter containing 1400.s of water (see sketch at night) First, a 8.000 y tablet of benzoic acid (C, H.CO,11) is put into the "bomb" and turned completely in an excess of oxygen. (Benzoic acid is known to have a heat of combustion of 26.454 /2.) The temperature of the water is observed to rise from 16.00 C to 48.86 Cover a time of 5.7 minutes Next, 5.6.20g of ethanol (C.HOH) are put into the "bomb and uimtarly completely bumed in an excess of oxygen This time the temperature of the water rises from 16.00 to 4149 Use this information, and any other information you need from the ALEKS Data resource, to answer the questions below about this reaction A 'bomb calorimeter CH,OH() + 30,6) -- 200,6) - 3H.06) Be sure any of your answers that are calculated from measured data are rounded to the correct number of significant digits Note for advanced students: It's possible the student did not do these experiments sufficiently carefully, and the values you calculate may not exactly match published values for this reaction
Is this reaction exothermic endothermic or nether? exothermic endothermic X s 2 ther If you said the reaction was exothermic or endothermic calculate the amount of best that was released or absorbed by the reaction in the second experiment. lu Calculate the reaction enthalpy per mole C,H,OHL 0 mol
