A student runs two experiments with a constant-volume "bomb" calorimeter containing 1300. g of water (see sketch at right). thermometer stirren First, a 5.000 g tablet of benzoic acid (CH,C0,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,0) 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 Use this information, and any other information you need from the ALEKS Data resource, to answer the questions below about this reaction: "bomb" A "bomb" calorimeter. 2 C,H,0(g) + 50,(g) 4 CO,(g) + 4 H,0(g) Be sure any of your answers that are calculated from measured data are rounded to the correct number of significant digits.
