questions A 'bomb calorimeter below about this reaction: + CH() + 30,6) - 200,6) + 2H,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 exothermic endothermic 0.0 X Is this reaction exothermic, endothermic, or neither? neither f you said the reaction was exothermie or endothermic calculate the amount or heat that was OK or the . 0 mol Calculate the reaction enthalpy AH. per mole of Co, Check Explanation
OTHERMOCHEMISTRY Calculating heat of reaction from bomb calorimetry dato A student runs two experiments with a constant-volume "bomb" calorimeter containing 1000. g of water (see sketch at night) First, a 5.000 g tablet of benzoic acid (CH_CO,H) 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 kJ/g.) The temperature of the water is observed to rise from 19.00 °C to 46.56 °C over a time of 13.9 minutes. Next, 5.230 g of ethylene (C, H.) are put into the "bomb" and similarly completely burned in an excess of oxygen This time the temperature of the water rises from 19.00 C to 69.36 °C. Use this information, and any other information you need from the ALEKS Data resource, to answer the
