Calculate the molar enthalpy: divide mass of fuel/Mr. Then divide the heat given out by that number. Example from BBC Bitesize: “The energy from burning 0.5 g of propane was transferred to 100 cm 3 of water to raise its temperature by 20°C. Calculate the enthalpy change (in kJ), and then use this to calculate the molar enthalpy change (in kJ ...

Calculate the overall energy change for this reaction and use this value to explain why the reaction is endothermic. Answer: Calculate the energy in. 436 + 151 = 587 (kJ) Calculate the energy out. 2 x 295 = 590 (kJ) Calculate the energy change. 587 - 590 = -3 (kJ) The reaction is exothermic because: More energy is released than taken in

kinetic energy. ELLIE: And you can calculate the kinetic energy of a moving object using an equation. So grab your pen and paper to write this one down. Kinetic energy equals 0.5 multiplied by mass multiplied by speed squared. Let me repeat that in case you didn't get the chance to write it down. Kinetic energy, which is measured in Joules ...
