A calorimeter initially contains 165.0 mL of water at 21.3oC. When 2.72 g K is added to the water, the temperature of the resulting solution rises to a maximum of 47.8oC. The reaction that occurs is:2K(s)+H2O(l)→2KOH(aq)+H2(g) Assuming no heat exchange between the calorimeter and the surroundings, calculate the heat of reaction, qreaction, in joules. (Use the total solution mass for the calculation, assume the density of water is 1.00 g/mL and the specific heat of the solution is 4.18 J/(g oC).  J
