Question

In a constant-pressure calorimeter, 50.0 mL of 0.340 M Ba(OH)2 was added to 50.0 mL of 0.680 M HCl. The reaction caused the temperature of the solution to rise from 23.69 °C to 28.32 °C. If the solution has the same density and specific heat as water, what is ΔH for this reaction (per mole of H2O produced)? Assume that the total volume is the sum of the individual volumes.

Answer 1

The heat produced in the constant pressure calorimeter is going to be equal to -ΔH, which is mass*specific heat*ΔT. Mass = density *volume.

Answer 2

Since the result should be per mole of H2O produced, we will need to write the balanced reaction.
