Astudent runs two experiments with a constant-volume "bomb" calorimeter containing of water (see sketch at right). first, a tablet of benzoic acid is put into the "bomb" and burned completely in an excess of oxygen. (benzoic acid is known to have a heat of combustion of .) the temperature of the water is observed to rise from to over a time of minutes. next, of ethanol are put into the "bomb" and similarly completely burned in an excess of oxygen. this time the temperature of the water rises from to . 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. 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.
