In а cоffee cup cаlоrimeter, 250.0 mL оf 1.00 M NаOH was added to 250.0 mL of 1.00 M HCl, and the temperature of the solution increased from 23.4° C to 30.4° C. Assume that the solution has a density of 1.00g/mL and a specific heat capacity of 4.184 J/g°C. Determine ΔH for this reaction: NaOH(aq) + HCl(aq) → H2O(l) + NaCl(aq)
