Question
![A student runs two experiments with a constant-volume "bomb" calorimeter containing 1300. g of water (see sketch at
right).
thermometer
stirrer
First, a 5.000 g tablet of benzoic acid (C,H,CO,H) is put into the "bomb" and burned completely in an excess of
water
oxygen. (Benzoic acid is known to have a heat of combustion of 26.454 kJ/g.) The temperature of the water is
insulation
observed to rise from 23.00 °C to 43.76 °C over a time of 6.8 minutes.
Next, 4.260 g of acetaldehyde (C,H,O);
are put into the "bomb" and similarly completely burned in an excess of
oxygen. This time the temperature of the water rises from 23.00 °C to 38.43 °C.
chemical reaction
"bomb"
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.
2C,H,0(g) + 50,(g) → 4CO,(g) + 4 H,O(g)
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.
O exothermic
Is this reaction exothermic, endothermic, or neither?
O endothermic
O 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.
