A simple coffee-cup calorimeter is often used to determine the amount of heated released when an acid is neutralized by a base. When 75.0 g of 2.00 M hydrobromic acid (HBr) is neutralized with 75.0 g of 2.00 M potassium hydroxide (KOH), the temperature of the solution increases from 20.0 °C to 33.0 °C. Using a specific heat capacity of the mixture of 4.2 J/g °C, how much heat in kJ is released in this reaction, assuming the calorimeter does not absorb any heat and that there is no heat exchange between the calorimeter and the surrounding air.

A 50-mL solution of a dilute AgNO3 solution is added to 100 mL of a base solution in a coffee-cup calorimeter. As Ag2O(s) precipitates, the temperature of the solution increases from 23.78 C to 25.19 C. Assuming that the mixture has the same specific heat as water and a mass of 150 g, calculate the heat q.
