Question

When 50.0 g of an aqueous solution of reagent 1 at 24.1oC is added to 100.0 g of of an aqueous solution of reagent 2 at 24.1oC in a calorimeter, the temperature increases to 29.9oC as a reaction proceeds.  Assuming the specific heat of the solution and products is 4.20 J/(goC), calculate the heat change (in joules) of the reaction.
