Enter your answer in the provided box. A quantity of 1.922 g of methanol (CH3OH) was burned in a constant-volume bomb calorimeter. Consequently, the temperature rose by 4.46°C. If the heat capacity of the bomb plus water was 9.20 kJ /°C, calculate the molar heat of combustion of methanol. kJ/mol
A quantity of 1.922 g of methanol (CH3OH) was burned in a constant-volume bomb calorimeter. Consequently, the temperature rose by 5.52°C. If the heat capacity of the bomb plus water was 8.75 kJ / °C, calculate the molar heat of combustion of methanol.
Enter your answer in the provided box. The enthalpy of combustion of benzoic acid (CH COOH) is commonly used as the standard for calibrating constant-volume bomb calorimeters; its value has been accurately determined to be -3226.7 kJ/mol. When 3.0653 g of benzoic acid are burned in a calorimeter, the temperature rises from 21.84°C to 24.67°C. What is the heat capacity of the bomb? (Assume that the quantity of water surrounding the bomb is exactly 2250 g.) kJ/°C
2. 1.487 g of methanol (CH3OH, a liquid at room temperature) is completely combusted at 25 °C in a bomb calorimeter with a heat capacity of 10.22 kJ/°C. The final temperature is found to be 28.291 °C. a. Calculate the standard heat of combustion of CH2OH(D) (ACH ) in kJ/mol at 25 °C. b. Calculate the standard heat of formation of CH3OH() (AFH ) in kJ/mol at 25 °C.
