Question 14

An industrial chemist uses a flow calorimeter to determine the energy released during a continuous neutralization reaction. The temperature of the effluent water stream increases by 13.2∘C13.2^{\circ}\text{C}13.2∘C.

The heat energy transferred to the water stream per minute can be calculated using the equation:

heat energy (J)=840×temperature rise \text{heat energy (J)} = 840 \times \text{temperature rise} heat energy (J)=840×temperature rise

Calculate the heat energy, in joules, transferred to the water stream per minute.
