In the lab you dissolve 3.050 g of CaCl2(s) in 190.0 g of water in a coffee cup calorimeter at 22.4 °C. The temperature to rises to 25.8 °C.a. What is the heat involved in the dissolution, assuming the specific heat of the resulting solution is 4.184 J/g °C? (Hint – add the masses to get the total mass of solution)b. Is the reaction exothermic or endothermic?q = Cs m ΔTShow your work.

Determine the change in temperature of a cup (382.10 g) of coffee at 90.2 °C when a 45.22 g silver spoon (specific heat 0.235 J/g °C) at 22.0 °C is placed in the coffee and they reach the same temperature? Assume that the coffee has the same specific heat capacity as water (4.184 J/g °C).q=m Cs ΔTShow your work.
