A student runs two experiments with a constant volume "bomb calorimeter containing 1000 x of water te sketch at right), First, a 6.000 g tablet of benzoic acid (CH.COH) is put into the bomb and burned completely in an excess of oxygen. (Benzoic acid is known to have a heat of combustion of 26 454) The temperature of the water is observed to rise from 15.00 °C to 48.07 "Cover a time of 5.2 minutes Next, 4.860 g of acetylene (CH) are put into the bomb and similarly completely burned in an excess of oxygen This time the temperature of the water rises from 15.00 C to 66.29 C, Use this information, and any other information you need from the Aleks Duta resource, to answer the questions below about this reaction ch Abomb calorimeter 2C,H,(8) + 50,6) -- 400,() + 2H,00 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 exothermic endothermic Is this reaction exothermic endothermic, or neither? c. neither If you said the reaction was exothermic or endothermic, calculate the amount of heat that was released or absorbed by the reaction in the second experiment. o Calculate the reaction enthalpy A. per mole of CH, mol Sub
