3. Consider the reaction: Nis) + Cu 2+ (aq) Ni 2+ (aq) + Cus) AH = -128.4 kJ This reaction is carried out in a coffee-cup calorimeter using 125g of water. The copper formed weighs 1.00g. Calculate the temperature change of the water, AT, (Specific heat (C) water = 4.18J/g-ºC) Hint: work backwards, start with the copper formed and its enthalpy change.
