A 1.103 g sample of a gaseous carbon–hydrogen–oxygen compound that occupies a volume of 582 mL at 765.5 Torr and 25.00 °C is burned in an excess of O₂(g) in a bomb calorimeter. The products of the combustion are 2.108 g CO₂(g), 1.294 g H₂O(l), and enough heat to raise the temperature of the calorimeter assembly from 25.00 to 31.94 °C. The heat capacity of the calorimeter is 5.015 kJ/°C. Write an equation for the combustion reaction, and indicate ¢rH° for this reaction at 25.00 °C.
