In a constant‑pressure calorimeter, 50.0 mL of 0.350 M Ba(OH)2 was added to 50.0 mL of 0.700 M HCl.
The reaction caused the temperature of the solution to rise from 22.17 ∘C
to 26.94 ∘C. If the solution has the same density and specific heat as water (1.00 g/mL and 4.184J/g⋅K,) respectively), what is Δ𝐻 for this reaction (per mole H2O produced)? Assume that the total volume is the sum of the individual volumes.
