Chemistry

Use the following information to answer questions 5-10. Astudent determined the heat of neutralization of copper (II)sulfate (CuSO4) mixed with potassium hydroxide (KOH) using theprocedure described part 2 of this experiment. A 150.0 mL sample ofa 1.50 M solution of CuSO4 was mixed with a 150.0 mL sample of 3.00M KOH in a coffee cup calorimeter. The temperature of bothsolutions and the calorimeter was 25.2 °C before mixing and 31.3 °Cafter mixing. The heat capacity of the calorimeter is 24.2 J/K.Calculate the heat of reaction (ΔHrxn) for this reaction in unitsof J/mole of copper (II) hydroxide (Cu(OH)2). Assume the solutionis dilute enough that the specific heat capacity and density of thesolution is the same as that of water, 4.18 J/g∙K and 1.00 g/mLrespectively. Calculate the number of moles of copper (II)hydroxide (Cu(OH)2) formed during this reaction. Assume thereaction goes to 100% completion.
