When 22.00 mL of 0.5000 M H_2SO_4 is added to 22.00 mL of 1.000 M kOH in a coffee-cup calorimeter at 23.50 degree C, the temperature rises to 30.17 degree C. Calculate delta H of this reaction. (Assume that the total volume is the sum of the individual assumes and that the density and specific heat capacity of the solution are the same for pure water.) (d for water = 1.00 g/mL; c for water - 4.184 J/g degree C.)...

The reaction of an acid such as HCl with a base, such as NaOH, in water is an exothermic reaction. HCl(aq) + NaOH(aq) ---> NaCl(aq) + H2O In one experiment, a student placed 55.0 mL of 1.00 M HCl in a coffee-cup calorimeter and carefully measured its temperature to be 35.5oC. To this was added 55.0 mL of 1.00 M NaOH solution whose temperature was also 35.5oC. The mixture was quickly stirred, and the student noticed that the temperature of...
