Example 5.5b: Heat Produced by an Exothermic Reaction
When 100 mL of 0.200 M \(\ce{NaCl(aq)}\) and 100 mL of 0.200 M \(\ce{AgNO3(aq)}\), both at 21.9 °C, are mixed in a coffee cup calorimeter, the temperature increases to 23.5 °C as solid \(\ce{AgCl}\) forms. How much heat is produced by this precipitation reaction? What assumptions did you make to determine your value?
