question Diesel is the fuel used in diesel engines. Diesel is actually a mixture of hydrocarbons: some are cyclic, but most are long chains. The average chemical formula for diesel is C12H23(1). 2. A scientist wants to determine the energy available from diesel. A sample of diesel fuel is burned in a tin calorimeter. The following data was collected from the experiment. Mass of diesel burned. 3.69 g Mass of tin calorimeter 1.73 kg Mass of water in calorimeter 455 g Initial temperature of water 21.4°C Final temperature of water 83.7°C Using the experimental evidence given, determine the molar enthalpy of combustion for diesel fuel. (3 marks) Use this information to including the energy as a term in the following equation showing the combustion of diesel. (1 mark) 4 C12H23(1) + 71 O2(g) → 48 CO2(g) + 46 H₂O(g) Your answer:
