In the calorimetry experiment, what will happen if the temperature was recorded prior to the stabilization of the temperature reading? Select one: O a. Magnitude of calculated AH < actual value O b. There is no need to wait for the stabilization of the temperature reading because it will not have much effect on the computed value. O c. Magnitude of calculated AH = actual value O d. Magnitude of calculated AH > actual value

Use the References to access important values if needed for this question. A bomb calorimeter, or a constant volume calorimeter, is a device often used to determine the heat of combustion of fuels and the energy content of foods. In an experiment, a 0.3163 g sample of azulene (C1₁0Hg) is burned completely in a bomb calorimeter. The calorimeter is surrounded by 1.061x10³ g of water. During the combustion the temperature increases from 23.18 to 25.79 °C. The heat capacity of water is 4.184 J g-¹°C-1. MindTap - Cenga X References The heat capacity of the calorimeter was determined in a previous experiment to be 797.7 J/°C. Molar Heat of Combustion = Submit Answer Assuming that no energy is lost to the surroundings, calculate the molar heat of combustion of azulene based on these data.

Esc ||| = OTHERMOCHEMISTRY A student runs two experiments with a constant-volume "bomb" calorimeter containing 1200. g of water (see sketch at right). Calculating heat of reaction from bomb calorimetry data First, a 5.000 g tablet of benzoic acid (C6H,CO₂H) 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 16.00 °C to 38.96 °C over a time of 9.2 minutes. 2 4. Next, 5.730 g of acetaldehyde (C₂H₂O) are put into the "bomb" and similarly completely burned in an excess of oxygen. This time the temperature of the water rises from 16.00 °C to 42.19 °C. 84°F Sunny Use this information, and any other information you need from the ALEKS Data resource, to answer the questions below about this reaction: FI Explanation Is this reaction exothermic, endothermic, or neither? 4- F₂ Check 2C₂H4O(g) + 50₂(g) 4CO₂(g) + 4H₂O(g) Be sure any of your answers that are…
