a) A 50.0 mL sample of a 1.00 M solution of CuSO4 is mixed with 50.0 mL of 2.00 M KOH in a calorimeter. The temperature of both solutions was 18.1 oC before mixing and 39.1 oC after mixing. The heat capacity of the calorimeter is 12.1 J/K. From these data, calculate ΔH for the process:
CuSO4(1M)+ 2KOH(2M) →Cu(OH)2(s) + K2SO4(0.5M)
Assume that the specific heat and density of the solution after mixing are the same as those of pure water and that the volumes are additive.
b) What is 30Hz, in joules?
