WebQuestion: Question: When 5.12 g of NaOH were dissolved in 51.55 g of water in a calorimeter at 24.5 °C, the temperature of the solution increased to 49.8 °C. Part C: Determine the heat given off by the dissolution of NaOH, 9rxn in J (recall qrxn = -9H20). If this quantity is negative, ensure you include a "-"in your answer. WebThere are two methods for distinguishing between exothermic and endothermic reactions. Monitor temperature change. When energy is released in an exothermic reaction, the temperature of the reaction mixture increases. When energy is absorbed in an endothermic reaction, the temperature decreases. You can monitor changes in temperature by placing ...
