In a coffee-cup calorimeter, 120.0 ml of 1.2 m and 120.0 ml of 1.2 m are mixed. both solutions were originally at 24.3c. after the reaction, the final temperature is 32.3c. assuming that all the solutions have a density of 1.0 and a specific heat capacity of 4.18 j/cg, calculate the enthalpy change for the neutralization of by . assume that no heat is lost to the surroundings or to the calorimeter.
