The reaction between 50.0g dilute HCl(aq) and 50.0g dilute NaOH(aq) is carried out in a calorimeter. the heat capacity of the calorimeter has been determined to be 24.0J/degreeC. if the temperature of the system increases by 6.0C what is the heat generated(qrxn) by the reaction?
since the solutions are dilute, assume the heat capacity and the density of the final solution are those of H2O.
My teacher gave us the answer, it is -2.65x10^3J.
