2. A complete combustion reaction occurs between 37.5 g of C4H10, butane gas and oxygen gas and produces water vapour and carbon dioxide gas. All the energy generated in the combustion reaction heats up the 35 kg of water in a very large bomb calorimeter. The molar enthalpy of combustion of butane is -2877.5 kJ/mol. cH20 = 4.184 J/ (g°C) a) Write a thermochemical equation. b) What is the change in temperature?
