< Question 11 of 14 > In a constant-pressure calorimeter, 75.0 mL of 0.920 M H2SO4 was added to 75.0 mL of 0.300 M NaOH. The reaction caused the temperature of the solution to rise from 21.12 °C to 23.16 °C. If the solution has the same density and specific heat as water (1.00 g/mL and 4.184 J/(g · °C), respectively), what is AH for this reaction (per mole of H0 produced)? Assume that the total volume is the sum...
