5) When 45.0mL of 1.20M sulfuric acid (H2SO4) are added to 130.0mL of 1.00M sodium hydroxide, the temperature of the mixture increases from 25.0°C to 39.5°C. Assuming the final mixture has a density of 1.00g/mL, a specific heat capacity of 4.184 J/g°C and that no heat is absorbed by the calorimeter: a) Determine the limiting reagent of the reaction. 12 b) The molar enthalpy of the reaction, in kilojoules per mole of the limiting reagent. 12 c) Write the balanced thermochemical equation for the reaction including the value of AH. 12
