Suppose you use a coffee cup calorimeter to measure the heat released in the neutralization reaction between sodium hydroxide and hydrochloric acid. Given the data in the table below, calculate q_rxn. The specific heat of water is used at 4.184 J/g°C. Based on the value and sign, is heat released or absorbed in the reaction?
Initial temperature in the calorimeter (°C): 22.0
Final temperature in the calorimeter (°C): 27.5
Mass of the total solution in the calorimeter (g): 98.240
Calorimeter constant (J/°C): 24.7
