Document Summary
A 0. 005637-mol sample of an organic compound was burned in oxygen in a bomb calorimeter. The temperature of the calorimeter increased from 24. 9 o c to 28. 8 o c. if the heat capacity of the calorimeter is. 4. 90 kj ( o c) -1 , then what is the constant volume heat of combustion of this compound, in kilojoules per mole (remember to include a + or - sign in your answer, as appropriate. ) Do not include units as part of your answer. 3 piece of brass at an initial temperature of 153 o c is dropped into an insulated container with 186. 9 grams of water initially at 24. 4 o c. What will be the final temperature of the brass-water mixture? (the specific heat of water is. Enter only numbers in your answer. (do not include units. ) 105. 84 * 0. 385 j(tf 153) + 186. 9 g (tf 24. 4) * 4. 184 j = 0. 40. 74844t 6234. 5052 + 781. 9896t - 19080. 546 = 0.
