Transcribed Image Text:rst, a 8.000 g tablet of benzoic acid (C6H5CO₂H) 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 21.00 °C to 62.82 °C over a time of 9.0 minutes.
Next, 4.760 g of acetaldehyde (C2H4O) are put into the "bomb" and similarly completely burned in an
excess of oxygen. This time the temperature of the water rises from 21.00 °C to 43.17 °C.
Use this information, and any other information you need from the ALEKS Data resource, to answer the
questions below about this reaction:
->
2C2H4O(g) + 502(g) → 4CO2(g) + 4H₂O(g)

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 neither?
exothermic
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.
