9 080 LAB EXERCISE 11.D Testing A, Hᵒ from Formation Data The molar enthalpies of formation method was created earlier in this section from Hess' law. Both problem-solving methods are consistent with the law of conservation of energy. This lab exercise tests this new method against evidence gathered from calorimetry. Purpose The purpose of this problem is to test the use of molar enthalpies of formation as a method of predicting the enthalpy change of a reaction. Problem What is the standard molar enthalpy of combustion of methanol? Report Checklist O Purpose O Problem O Hypothesis ● Prediction O Design O Materials O Procedure O Evidence ● Analysis Evaluation (2, 3) Design Methanol is burned in excess oxygen in a special calorimeter. Assume that liquid water is produced. Evidence mass of methanol reacted = 4.38 g mass of water equivalent to calorimeter = 2.60 kg initial temperature of calorimeter = 20.4 °C final temperature of calorimeter = 27.9 °C (Note that the calorimeter has the…
Sample Bomb Calorimetry Problem: A bomb calorimeter was heated for 568 seconds with a 15.00 watt heater 1J (1 watt = s ). The temperature of the calorimeter rose by 2.00 C. A 0.455-g sample of solid sucrose (CızH22O1) was then burned in excess molecular oxygen gas in the same calorimeter. The temperature increased from 24.49 C to 26.25 C. Calculate: a) the heat capacity for the calorimeter b) the molar hcat of combustion for sucrose (both AHo and AU) c) the number of calories in a gram of sucrose (Note: 1 calorie = 4.184 J) Solution:

O Macmillan Learning An ideal gas expands from 28.0 L to 92.0 L at a constant pressure of 1.00 atm. Then, the gas is cooled at a constant volume of 92.0 L back to its original temperature. It then contracts back to its original volume without changing temperature. Find the total heat flow, in joules, for the entire process. total heat flow:
