the fuel might not comb ust Practice Questions OL Briefly describe an experiment that could be carried out to find the enthalpy change of a reaction. 02 Why is the enthalpy change determined in a laboratory likely to be lower than the value shown in a OL What equation is used to calculate the heat change in a chemical reaction? Exam Questions OLA 50.0 cm' sample of 0.200 mol dm' copper(II) sulfate solution placed in a polystyrene beaker gave a temperature increase of 2.60 K when excess zinc powder was added and stirred. Calculate the enthalpy change when 1 mole of zinc reacts. Assume that the specific heat capacity for the solution is 4.18 J g K-. Ignore the increase in volume due to the zinc. -3 The equation for the reaction is: Zn+CUSO → Cu + ZNSO 4(aq) 4(aq) 02 a) Explain why bond enthalpies determine whether a reaction is exothermic or endothermic. b) Calculate the temperature change that should be produced when 1.000 kg of water is heated by burning 6.000 g of coal.
