When a 13.3 g sample of NaOH(s) dissolves in 386.0 mL water in a coffee cup calorimeter, the temperature of the water changes from 22.5°C to 31.4°C. NaOH (8) — Na* (aq) + ОН (аq) Assuming that the specific heat capacity of the solution is the same as for water (4.184 J/g . °C) and the density of the solution is 1.031 g/mL, calculate the following. the heat transfer from system to surroundings (in J) a. b. AH for the reaction (in kJ) kJ
