When 4.98 g of NaOH was dissolved in 49.72 g of water in a calorimeter at 23.7 degrees celsius, the temperature of the solution went up to 50.1 degrees celsius. a. is this dissolution reaction exothermic? why? b. calculate qH2O using equation 1, c. find difference in H for the reaction as it occured in the calorimeter, d. find difference in H for the dissolution of 1.00 g NaOh in water, e. find difference in H for the dissolution of 1 mole of NaOH in water, f. given that NaOH exists as Na+ and OH- ions in solution, write the equation for the reaction that occurs when NaOH is dissolved in water, g. Given the following heats of formation, difference in H, final, in kJ per mole, has obtained from a table of difference H final data, calculate the difference H for the reaction in part F. Compare your answer with the result obtained in part E. NaOH(s), -425.6; Na+ (aq), 240.1; OH-(aq), -230.0
