When 50.0 cm^3 of 2.0 m hcl was added to 50.0 cm^3 of 2.0 m naoh solution in a simple calorimeter, there was a rise in temperature of 13.0°c . (assume that the specific heat capacity and density of the solution are 4.2j g^-1 k^-1 and 1.0 g cm^-3 respectively.) (a) calculate the enthalpy change of neutralization for one mole of water formed (solved : -1201.2 kj mol^-1) (b) what would be the temperature rise if 100.0 cm^3 of 2.0 m hcl were added to 100.0 cm^3 of 2.0 m naoh solution? explain your answer with the aid of calculations
