12. A cup of coffee (mass = 125 g and initial temperature of 95 °C) is sitting on a table. You want to cool it off to 88 °C so you can take a drink. You slowly stir it with a metal spoon (mass = 75 g at an initial temperature of 18 °C and specific heat = 0.14 cal/g °C.). What is the specific heat of the coffee?

When 27.0 mL of 0.500 M H2SO4 is added to 27.0 mL of 1.00 M KOH in a coffee-cup calorimeter at 23.50°C, the temperature rises to 30.17°C. Calculate ΔH of this reaction. (Assume that the total volume is the sum of the individual volumes and that the density and specific heat capacity of the solution are the same as for pure water.)
