Question 10 1.5 pts An aqueous solution of HCl is added to an aqueous solution of NaOH in a coffee cup calorimeter. The reaction is that of neutralization between the acid and the base: HCI + NaOH + H2O + Naci To calculate the approximate enthalpy change for this reaction using q = m.CAT, what value should the student give to C in the equation? The student must use the heat of formation of...
