Constants Periodic Table Part A An alternative approach to bomb calorimetry is to establish the heat capacity of the calorimeter exclusive of the water it contains. The heat absorbed by the water and by the rest of the calorimeter must be calculated separately and then added together A1 148 g sample of benzoic acid is burned in excess O(g) in a bomb immersed in 1181 g of water. The temperature of the water rises from 2496 to 30.25...
Under constant-volume conditions the heat of combustion of glucose (C6H12O6) is 15.57 kJ/g. A 3.800-g sample of glucose is burned in a bomb calorimeter. The temperature of the calorimeter increased from 20.94 °C to 24.77 °C Review Ca Part A What is the total heat capacity of the calorimeter? ? kJ C Request Answer Submit Part B If the size of the glucose sample had been exactly twice as large. what would the temperature change of the calorimeter have been?...
③ 28 of 32 Review Constants Periodic Table Part A Which statement is true of the temperature of the two substances when they reach thermal equilibrium? (Assume no heat loss other than the thermal transfer between the substances.) The final temperature of both substances will be closer to the initial temperature of substance A than the initial temperature of substance B. The final temperature of substance A will be greater than the final temperature of substance B. The final temperature...
