Q2. A student used Hess's Law to determine a value for the enthalpy change that occurs when anhydrous copper(II) sulfate is hydrated. This enthalpy change was labelled 4H by the student in a scheme of reactions. anhydrous copper(II) sulfate AH₁ State Hess's Law. water water AHoxp AH--156 kJ mol-¹ AH₂+12 kJ mol-1 hydrated copper(II) sulfate AH₂ copper(II) sulfate solution water Write a mathematical expression to show how AH. AHI and AH2 are related to each other by Hess's Law. (c) Use the mathematical expression that you have written in part (b), and the data book values for the two enthalpy changes AH₁ and AH; shown, to calculate a value for AHor e (1) e
